->''"I find that if you take the various popular song forms to their logical extremes, you can arrive at almost anything from the ridiculous to the obscene--or, as they say in [[UsefulNotes/NewYorkCity New York]], sophisticated."''
-->--'''Tom Lehrer'''

Thomas Andrew Lehrer (born April 9, 1928) is an American satirist who managed to achieve remarkable popularity and impact on popular culture, despite having produced only three albums' worth of material in the [[TheFifties 1950s]] and [[TheSixties '60s]] before retiring to a life in academia as a mathematician. Lehrer's pieces often take the form of witty parodies of various popular song forms. Other common themes in his work are disapproval of [[ArsonMurderAndJaywalking nuclear war, Cold War politics, and folk singing]]. Of course, he undercuts that last by putting forth as perfect a rendition of such songs as can be done with only a piano ("imagine that I am playing an 88-string guitar", as he said in his intro to "The Folk Song Army," on his 1965 album ''That Was the Year That Was'') as accompaniment.

He also wrote 10 songs for the children's educational series ''Series/TheElectricCompany1971''.

Lehrer is still alive, and occasionally performing. At the 80th birthday party of a fellow mathematician and friend Irving "Kaps" Kaplansky, [[http://www.archive.org/details/lehrer he dusted off a handful of mathematics songs]] to an appreciative crowd of students and fellow mathematicians.

[[Music/WeirdAlYankovic "Weird Al" Yankovic]] cites Tom Lehrer as one of his inspirations, while Creator/DrDemento has described him as "the greatest musical satirist of the 20th Century." Lehrer's own inspirations notably include Creator/GilbertAndSullivan, Creator/DannyKaye and Music/ColePorter. He also claimed to have invented the [[http://en.wikipedia.org/wiki/Gelatin_dessert#Gelatin_shots Jell-O shot]] as a way of circumventing military base regulations, though the idea goes at least as far back as the 1862 book, ''How to Mix Drinks or The Bon-Vivant’s Companion''.

!!Mr. Lehrer's works display examples of:

* ActingUnnatural: In one of Tom Lehrer's compositions for ''Series/TheElectricCompany1971'', "L-Y", this trope comes into play in the second verse. Enhanced by the animation for the song, in which the "secret agent man" leans against the safe he is trying to open while playing with a yo-yo and smiling ear to ear.
-->You're a secret agent man\\
Who's after the secret plan\\
How do you act so they don't know you're a spy?\\
Ah-normally ''(NotSoInnocentWhistle)'' Normally ''(whistles again)''\\
Normal... L-Y!
* TheAggressiveDrugDealer: "The Old Dope Peddler"
* AlmaMaterSong:
** "Bright College Days".
** "Fight Fiercely, Harvard". It is actually a parody of a FootballFightSong, but Harvard is Tom Lehrer's alma mater.
* AntiChristmasCarol: "A Christmas Carol".
* AntiLoveSong: Numerous examples.
* ArsonMurderAndJaywalking: The final verse of "The Irish Ballad":
-->And when at last the police came by\\
Her [[{{Understatement}} little pranks]] she did not deny\\
For to do so she would have had to lie...\\
And lyin' she knew was a sin.
** Inverted with the the review-quotes he included on at least one of his album covers:
--->"More desperate than amusing" — New York Herald Tribune\\
"He seldom has any point to make except obvious ones" — The Christian Science Monitor\\
"Mr. Lehrer's muse is not fettered by such inhibiting factors as taste." — New York Times\\
"Obvious, jejune, and remarkably unsophisticated." — London Evening Standard\\
[[DamnedByFaintPraise "Plays the piano acceptably"]] — The Oakland Tribune
* BeastlyBloodsports: "In Old Mexico"
* BestialityIsDepraved:
** From the introduction to "In Old Mexico":
---> He majored in animal husbandry until they... caught him at it one day.
** From "I Got It from Agnes":
---> She then gave it to Daniel, whose spaniel has it now.
* BilingualBonus: In the recorded version of "Lobachevsky", the reviews from ''Pravda'' and ''Izvestia'' are, respectively: "There once was a king who had a pet flea," the first line of Mussorgsky's "Song of the Flea", and "I must go where the Tsar himself goes on foot," a Russian idiom meaning "I have to go to the bathroom". Lehrer usually substituted nonsense when he performed before an audience whose members were likely to include Russian speakers.
* '''BlackComedy''': Lots and lots of examples, but "I Got It from Agnes" has this doozy: "Max got it from Edith, who gets it every spring/ [[ParentalIncest She got it from her daddy]], [[DaddysGirl who just gives her everything]]..."
** It [[SerialEscalation gets better]]: "She gave it to Daniel whose [[BestialityIsDepraved spaniel]] has it now/ Our dentist's even got it and we're '''''[[InstantSedation still]] [[BlackComedyRape wondering]] [[DudeShesLikeInAComa how]].'''''"
* BreadEggsMilkSquick: The commingling of the ordinary with the {{squick}} is a staple of his work.
** "My Home Town" begins with idyllic reminiscences of his home town and quickly slides into recalling "the guy who took a knife/and monogrammed his wife".
** "Be Prepared" exhorts Boy Scouts to be prepared for all situations...such as smoking dope and pimping out their own sisters.
** "I Hold Your Hand in Mine" sounds romantic, up to the lyrics "My joy would be complete, dear/If only you were here/But still I keep your hand/As a precious souvenir." And: "I hold your hand in mine, dear/I press it to my lips/I take a healthy bite from your dainty fingertips".
** His song "The Old Dope Peddler" sings admiringly of the cornerstone of any neighborhood, the Heroin Dealer. In more recent interviews, he's admitted that in retrospect he finds that particular song "chilling".
** "I Wanna Go Back to Dixie" does this as well. It's mostly an almost sweet, happy song about wanting to go back home...but it's after he includes the line "Ol' times there are not forgotten/Whuppin' slaves and selling cotton" that it gets dark.
** "Poisoning Pigeons in the Park" starts off like a lovely ode to springtime and young love, but when he suddenly starts the chorus, the song takes a major left turn into this trope, along with some LyricalDissonance because of the song ''still'' being sung the same way, despite the lyrics. He actually tries to justify this:
--->We've gained notoriety\\
And caused much anxiety\\
In the Audubon Society with our games.\\
They call it impiety\\
And lack of propriety\\
And quite a variety of unpleasant names.\\
But it's not against any religion\\
To want to dispose of a pigeon!
** Most of Tom Lehrer's songs, and their humor, stem from this trope.
* BunnyEarsLawyer: Aside from being a quirky satirist, he's a Harvard-educated mathematician and a ''very'' accomplished pianist.
* CheapHeat: Since ''That Was the Year That Was'' was recorded in San Francisco, he sings "the breakfast garbage that you throw into the bay, they drink at lunch in San Jose" in "Pollution" and gets an enthusiastic reaction from the crowd. The songbook ''Too Many Songs by Tom Lehrer'' suggests that anyone singing the song should similarly localize that line.
* CompetitionCouponMadness: Parodied in "It Makes a Fellow Proud to Be a Soldier".
* ConvenienceStoreGiftShopping: He mocks the practice in his Christmas Carol:
-->Relations sparing no expense'll\\
Send some useless old utensil\\
Or a matching pen and pencil.\\
[[SarcasmMode "Just the thing I need. How nice."]]\\
It doesn't matter how sincere it\\
Is, nor how heartfelt the spirit.\\
Sentiment will not endear it.\\
What's important is the price.
* CrapsackWorld: "My Home Town," although it could perhaps be "{{Crapsaccharine|World}}" given how fondly the narrator remembers it…
* CreepySouvenir: "I Hold Your Hand in Mine"
* DeadpanSnarker: "MLF"
-->Once all the Germans were warlike, and mean, but that couldn't happen again,
-->We taught them a lesson in 1918, and they've hardly bothered us since then!
** Pretty much the entirety of "Dr. Wernher Von Braun" is this, including such gems as "'once the rockets go up, who cares where they come down, that's not my department' says Wernher Von Braun."
* FilkSong: Virtually everything he wrote has been adopted as "Found Filk," notwithstanding--or perhaps in spite of--Lehrer's feelings about folk music. There have even been full Tom Lehrer Sing-Alongs.
* TheFilmOfTheBook: Parodied at least twice.
** "Lobachevsky" describes a film version of a ''mathematics textbook''...
--> "With Ingrid Bergman [or Bridget Bardot] playing the part of Hypotenuse."
** "Oedipus Rex", meanwhile, was a modest proposal for a title tune "which the people could hum" for the film of [[Theatre/OedipusRex the eponymous play]].
* {{Filth}}: The subject matter of "Smut".
* FriendToPsychos: In "My Home Town":
--->I remember Sam; he was the village idiot\\
And though it seems a pity, it\\
Was so\\
He liked to burn down houses just to watch the glow\\
And nothing could be done\\
Because he was the mayor's son
* GallowsHumor: His nuclear war songs.
* GettingCrapPastTheRadar:
** "I Got It from Agnes." What "it" is is never specified, but we can guess.
--->I love my friends, and they love me\\
We're just as close as we can be\\
And just because we really care\\
Whatever we get, we share.
** Sadly, Lehrer did ''not'' originally get this past the radar, as his recording of it was not released until 1997 as a bonus track on ''Songs & More Songs by Tom Lehrer'', a compilation rerelease of two albums from the 1950s. The first released recording of it was from the ''Tom Foolery'' soundtrack in 1980. However, Lehrer himself was responsible for the song's being unreleased at the time because he felt it was too racy, although he would perform it in nightclubs going back to the ''1950s''.
* TheGreatPoliticsMessUp: A lot of the GallowsHumor in his songs is predicated on the fact that nuclear war with the USSR and the subsequent TheEndOfTheWorldAsWeKnowIt was considered inevitable at the time.
* GrowOldWithMe: Satirized in "When You Are Old and Gray".
* HavingAHeart: "I Hold Your Hand in Mine" and "TheMasochismTango".
* HollywoodNewEngland: "The Elements":
-->These are the only ones of which the news has come to Hahvard,\\
And there may be many others but they haven't been discahvard.
* HumanHeadOnTheWall: "The Hunting Song":
-->''And there's ten stuffed heads in my trophy room right now,''
-->''Two game wardens, seven hunters, and a pure-bred guernsey cow.''
* ImAHumanitarian:
** "The Irish Ballad":
--->One day when she had nothing to do\\
She cut her baby brother in two\\
And served him up as an Irish stew\\
And invited the neighbours in
** "My Home Town":
--->I remember Dan, the druggist on the corner; he\\
Was never mean or ornery; he was swell\\
He killed his mother-in-law and ground her up real well\\
And sprinkled just a bit over each banana split
* InTheStyleOf: [[http://www.youtube.com/watch?v=7i4f8oohdi0 'Clementine']]
* InsultBackfire:
** His songs are well-liked among the more humorous folk and {{Filk}} singers.
** The Harvard University Band regularly performs his [[FootballFightSong fight-song]] parody "Fight Fiercely, Harvard" at football games.
** For himself, Lehrer was very fond of a review he'd once received, and loved to quote it: "Mr. Lehrer's muse is [[TheUnfettered not fettered]] by such inhibiting factors as taste."
* IWillFindYou: Given a suitably dark twist in "So Long Mom (I'm Off To Drop The Bomb)":
-->''I'll look for you when [[WorldWarIII the war]] is over''\\
[checks watch]\\
''An hour and a half from now!''
* JukeboxMusical: ''Tom Foolery''.
* KnowsAGuyWhoKnowsAGuy:
** An exaggeratedly long example in "Lobachevsky". See ListSong below.
** "I Got It from Agnes" in the sense of carnal knowledge.
* LeastRhymableWord: Multiple examples. Lehrer loves working around this.
* LethalChef: Referenced in "It Makes a Fellow Proud to Be a Soldier":
-->Our old mess sergeant's taste buds had been shot off in the war.\\
But his savory collations add to our ''esprit de corps''.\\
To think of all the marvelous ways\\
They're using plastics nowadays.\\
It makes a fella proud to be a soldier!
* ListSong:
** "The Elements" is ExactlyWhatItSaysOnTheTin; all of the chemical elements known at the time, set to "a possibly recognizable tune": "[[MajorGeneralSong The Major-General's Song]]" from ''Theatre/ThePiratesOfPenzance''.
** "Lobachevsky" also includes a verse that's largely a list of towns in the Soviet Union. "I have a friend in Minsk, who has a friend in Pinsk, whose friend in Omsk has friend in Tomsk with a friend in Akmolinsk!" That's not the complete list, by the way. And the return journey somehow manages to squeeze in two more cities that weren't mentioned the first time.
** "I Got It from Agnes": who got it from whom.
* LiteralMetaphor: "The Masochism Tango":
--> At your command\\
Before you here, I stand\\
My heart is in my hand... (Yecch!)
* ALoveToDismember: "I Hold Your Hand in Mine" and "The Masochism Tango".
* LyricalDissonance:
** "Poisoning Pigeons in the Park" is a bright, happy, song about [[ExactlyWhatItSaysOnTheTin guess what.]]
** Special mention has to go to "We Will All Go Together When We Go," a cheery, toe-tapping number about the complete extinction of the human race. And how that's a good thing because it means there'll be nobody left alive to feel sad about it afterward.
--->We will all go directly to our respective Valhallas\\
Go directly, do not pass Go, do not collect two hundred dolla's ...
** "So Long Mom" is also a song about nuclear war set to a cheerful tune. The narrator is a pilot in WorldWarIII adressing his mother:
--->While we're attacking frontally,\\
Watch Brinkley and Huntley\\
Describing contrapuntally\\
The cities we have lost.\\
No need for you to miss a minute\\
Of the agonizing holocaust. (Yeah!)
** His nuclear-war and nuclear-testing songs in general.
** ''Theatre/OedipusRex'':
--->There was a man though, who, it seems\\
Once carried this ideal to extremes,\\
He loved his mother and she loved him\\
And yet his story is rather grim...\\
[''merry melody'']
* MajorGeneralSong: Lehrer describes "The Elements" as "the names of the chemical elements set to a [[ToTheTuneOf possibly recognisable tune]]".
* TheMasochismTango: The TropeNamer. Ironically, however, the song itself isn't an example. [[ObligatoryBondageSong It's more about a really kinky couple.]]
* MeaningfulName: "Lehrer" is German for "teacher".
* TheMelBrooksNumber: Arguably could be called the Tom Lehrer number. Classical arrangement, orchestral backing (in at least two cases), plenty of GeniusBonus, and content that ranges from BlackComedy, GallowsHumor, ribald, or just caustic - but it's always hilarious.
* MidwordRhyme: Done constantly, and always for the RuleOfFunny. In an interview he once used this as a workaround for the infamous lack of rhymes with "orange": "Eating an orange/While making love/Makes for a bizarre enj-/oyment thereof."
* MoneySong: "Selling Out"
* MotorMouth: "New Math", "The Elements", and his research assignment in "Lobachevsky".
* MummiesAtTheDinnerTable: "I Hold Your Hand in Mine".
* MurderBallad: "The Irish Ballad".
* NoodleIncident: In the song "My Home Town," Tom Lehrer always omits a line while announcing something to the effect of, "We're recording tonight, so I'll have to leave this line out." (He subsequently admitted that he never found a satisfactory line, and found the implication that he wanted to say something so unspeakably racy that it had to be censored much funnier.)
* OedipusComplex: Has a song about [[Theatre/OedipusRex the Trope Namer]]. Lehrer probably deserves an award for rhyming "Rex" with "Complex".
* TheOldestProfession:
** "Now there's a charge for what she used to give for free in my home town".
** From "Be Prepared":
--> ''Don't solicit for your sister; that's not nice''
--> ''Unless you get a good percentage of her price''
* OverlyLongGag:
** In the song "When You Are Old and Grey," he uses so much "-ility" rhymes that he (intentionally) gets worn-out about three-quarters of the way through.
** Taken to PatterSong extremes in TheMusical production ''Tomfoolery''.
** Namely, the original song only has the following: debility, utility, mobility, possibility, probability, virility, fertility, desirability, liability, sterility, hostility, futility, agility, facility, senility, and ability. ''Tomfoolery'' adds: compatibility, fragility, advisability, durability, inflexibility, volatility, inconceivability, humility, nobility, puerility, indispensability, versatility, irresponsibility, juvenility, adorability, and imbecility.
* PainfulRhyme: Sometimes spectacularly so, and [[InvokedTrope entirely deliberate]]. For instance, these lines from "We Will All Go Together When We Go":
-->When you attend a funeral\\
It is sad to think that sooner or l...\\
...ater those you love will do the same for you\\
And you may have found it tragic\\
Not to mention other adjec...\\
...tives to think of all the weeping they will do
** Also, during "The Masochism Tango":
-->Your heart is hard as stone or mahogany.\\
That's why I'm in such exquisite ah-gony.
** Also the section from "A Christmas Carol" from the ConvenienceStoreGiftShopping part mentioned above.
** There are some truly rough ones in "(I'm Spending) Hannukah in Santa Monica":
-->Those Eastern winters, I can't endure 'em\\
So every year I pack my gear and come out here till Purim
-->Rosh Hashanah, I spend in Ari-''zah''-na\\
And Yom Kippur, way down in Mississippur...
* ParentalBonus:
** While most of his songs are still funny, there are lines he says that are rather topical to the 1960s. An example would be when he mentions that Massachusetts is the only state with ''three'' senators, it's because Robert Kennedy (from Massachusetts) happened to be a New York senator at the time.
** "New Math" was supposed to make fun of the new (at the time) substraction method, by using MotorMouth to make it look as incomprehensible as possible. While New Math was mostly abandoned, the subtraction method he demonstrates in the song actually stuck around, and nowadays, kids are taught using that "new" method. Kids will now understand perfectly the incomprehensible "new" method, but struggle trying to understand the normal "old" method because Lehrer didn't bother explaining it too much (since he assumed people would be familiar with the method) and, as Lehrer himself points out, the "old" method wasn't actually meant to be understood.
** The lead-in to "In Old Mexico" includes the line "... Where he majored in animal husbandry, until they ... [[BestialityIsDepraved caught him at it]] one day..." which kids probably won't get, but to adults is racy even by today's standards.
* PoesLaw: Lehrer responded to the award of the Nobel Peace Prize to Henry Kissinger by commenting that "satire is obsolete". (Rumors to the contrary notwithstanding, that's not why he quit performing. He had already quit because he was tired of touring and redoing the same songs over and over.)
* PollutedWasteland: The whole topic of "Pollution", which is a reversal of how Americans going overseas would be warned not to drink the water there, and how foreigners coming to America should prepare for it. Example:
--> If you visit American city,\\
You will find it very pretty.\\
Just two things of which you must beware:\\
Don't drink the water and don't breathe the air!\\
Pollution, pollution!\\
They've got smog and sewage and mud.\\
Turn on your tap\\
And get hot and cold running crud!
* ProtestSong: Parodied in "The Folk Song Army". Lehrer believed that protest songs were utterly useless and was fond of reminding people of how effective the satirical cabaret shows of Weimar Germany were against the Nazis. He did several songs satirizing political issues of the day, such as nuclear proliferation, and senator and former Hollywood star George R. Murphy's racist remarks during an interview and other such things, but these were more GallowsHumor than protests.
--> Remember the [[UsefulNotes/SpanishCivilWar war against Franco]],
--> that's the kind where each of us belongs.
--> Though he may have won all the battles,
--> we had all the good songs.
* {{Pyromaniac}}: From "My Home Town":
--> I remember Sam!
--> He was the village idiot
--> And though it seems a pity, it was so
--> He liked to burn down houses just to watch the glow
--> And nothing could be done
--> Because he was the mayor's son
* RecklessGunUsage: "The Hunting Song" talks about accidents usual for an opening of the hunting season. With a "recipe":
--> People ask me how I do it
--> And I say, "There's nothing to it!
--> You just stand there looking cute,
--> And when something moves … you shoot!"
* SanitySlippageSong: "I Hold Your Hand in Mine"
* SelfDeprecation: One album was named ''An Evening Wasted with Tom Lehrer''; another's cover quoted several unflattering reviews of his work, including one from the ''New York Times'' saying "Mr. Lehrer's muse is [[TheUnfettered not fettered]] by such inhibiting factors as taste."
** [[InsultBackfire He really liked that, and used to quote it often]].
** The liner notes for his albums would say, "If you did not enjoy this album, you will most definitely not enjoy (names of his other albums)."
** There's also the fact that he teaches at and went to Harvard and wrote "Fight Fiercely, Harvard" essentially saying how wussy he thinks Harvard is. Harvard ''itself'' plays the song at their games.
* ScaryMusicianHarmlessMusic: Inverted. Lehrer looks like the math professor he is, and his tunes are all happy, upbeat piano pieces, but egad, the lyrics!
* SerialEscalation: Each verse of "I Got it from Agnes" endeavours to be more controversial than the last, gradually implying DepravedBisexual tendencies, a [[ThreesomeSubtext gay threesome]], ParentalIncest, a man who [[BestialityIsDepraved bred with his dog]] and finally that their dentist raped one of them while they were under anaesthetic.
* SesameStreetCred:
** If you've only heard one song of Lehrer's, it's probably "Silent E" from ''Series/TheElectricCompany1971''. Beware: '''EarWorm.''' Or "L-Y" from the same show.
** Or maybe your Chemistry teacher introduced you to "The Elements".
*** "The Elements" has even been used in ''science documentaries''.
*** And now ''Series/TheBigBangTheory''.
*** And on the ''Series/{{NCIS}}'' episode "Ex-File."
*** And frequently, Creator/DanielRadcliffe will dust off the song from memory when he's a guest on daytime, evening, and late-night talk-shows, so does that mean Lehrer also has [[Franchise/HarryPotter Diagon Alley]] cred to his name?
* SesquipedalianLoquaciousness: Professor Lehrer would frequently utilize very elongated words and sophisticated language.
* ShoutOut: In some cases. For example, "Smut" has {{Shout Out}}s to two classic works of erotic literature, ''Literature/FannyHill'' and ''Literature/LadyChatterleysLover''. Lehrer also joked that he'd always wanted to write a mathematics textbook because he had a title he knew would sell a million copies: ''[[Literature/TropicOfCancer Tropic of Calculus]]''.
** Various recorded versions of "Lobachevsky" credit Creator/BrigitteBardot, Creator/IngridBergman, Creator/DorisDay, and Creator/MarilynMonroe as playing the hypotenuse in [[TheFilmOfTheBook the film version]] of ''The Eternal Triangle''.
* SouthernFriedPrivate: "It Makes a Fellow Proud to Be a Soldier"
* SubvertedRhymeEveryOccasion: "The Folk Song Army" and "My Home Town" being the two best examples.
* TakeMeToYourLeader: Spoofed in "Whatever Became of UsefulNotes/{{Hubert|Humphrey}}?":
-->"We must protest this treatment, Hubert"
-->Says each newspaper reader
-->As someone once remarked to [[Music/FranzSchubert Schubert]]
-->[[IncrediblyLamePun Take us to your Lieder]]
-->(sorry about that)
* TakeThat: A ''lot'' of his songs are attacks on someone or something, but as already noted folk-singers have been a repeated target, and his "ode" to [[PunchClockVillain Wernher]] [[ForScience von Braun]] also stands out.
* TakeThatAudience: At the end of "Oedipus Rex", his response to the audience applauding is "The outpatients are out in force tonight, I see".
* TeenGenius: He earned a bachelor's degree in Mathematics from Harvard. At 19. Yeah.
* ThoseWackyNazis: As mentioned above, he references Wernher von Braun's Nazi past:
-->Call him a Nazi, he won't even frown...
-->"Heh, Nazi Schmazi," says Wernher von Braun!
* ThreeChordsAndTheTruth: He has a dig at this trope in the spoken intro to "Folk Song Army":
--> "I have a song here which I realize should be accompanied on a folk instrument, in which category the piano does not, alas, qualify. So imagine, if you will, that I am playing an 88-string guitar."
** Then he does it again in the song itself, where he also pokes fun at the lyrical version:
--> The tune don't have to be clever,
--> And it don't matter if you put a couple extra syllables into a line.
--> It sounds more ethnic if it ain't good English,
--> And it don't even gotta rhyme--excuse me--rhyne.
* ToTheTuneOf: "The Elements" takes its melody from Creator/GilbertAndSullivan's "[[MajorGeneralSong I Am the Very Model of a Modern Major-General]]".
* TradingBarsForStripes: Referenced in "It Makes A Fellow Proud To Be A Soldier":
-->When Pete was only in the seventh grade, he stabbed a cop.\\
He's real R.A. material and he was glad to swap\\
His switchblade and his old zip gun\\
For a bayonet and a new M-1.
* TrophyHusband: "Alma", a ballad dedicated to socialite Alma Mahler Gropius Werfel, whom he praises for managing to marry three of the greatest minds of the day and having the raciest obituary he had ever had the pleasure of reading.
-->The first one she married was Mahler,
-->Whose buddies all knew him as Gustav.
-->And each time he saw her he'd holler:
-->"Ach, das ist the fräulein I [[PainfulRhyme moost have]]!"
* TheUnfettered: According a review by the New York Times which he proudly quotes: "Mr Lehrer's muse is not fettered by such inhibiting factors as taste".
* VerbalBackspace: "New Math" gets a gag out of a subtraction error:
-->And so you've got thirteen tens
-->And you take away seven,
-->And that leaves five...
-->[[{{Beat}} ...]]
-->Well, six actually...
-->But the idea is the important thing!
* ViewersAreGeniuses: The historical stuff nowadays, thanks to the topical aspect (see TheGreatPoliticsMessUp, ParentalBonus). His scientific songs, though, definitely qualify; in fact, before Lehrer even recorded an album, he performed the "[[http://www.haverford.edu/physics/songs/lehrer/physrev.htm Physical Revue]]" to a group of Harvard physics students.
* VisualPun: After singing the line "To thee we sing with our glasses raised on high" in "Bright College Days", Lehrer would take off his glasses and raise them.
* WackyFratboyHijinks: "Bright College Days"
* WithCatlikeTread: "O-U (The Hound Song)" from ''Series/TheElectricCompany1971''.
* WorldWarIII: "So Long Mom (I'm Off To Drop The Bomb)", or "We Will All Go Together When We Go" ([[BlatantLies "a rousing, uplifting song that's sure to cheer you up."]])
** The former hilariously visualized [[http://mocpages.com/moc.php/170603 here]]--in {{LEGO}}!
** And in "Who's Next".
** Let's not forget "The Wild West is Where I Want to Be", in which the narrator longs to return to the west even though most of it has been turned over to nuclear testing.
* YouMakeMeSic: In "Be Prepared", Lehrer admonishes young Boy Scouts, "Don't write naughty words on walls if you can't spell".
