In the video for You Probably Get That A Lot, Linnell goes completely mute near the end, leaving the rest of the band to play on. He then comes back to say the "-ly" in the word "spontaneously."
That's also in the Album Raises Troubling Questions remix.
There was an anecdote about falling for a Snipe Hunt-like trick that John Linnell used to routinely tell between songs during a tour in 1999: While in Rhode Island, someone recommended he go out to a particular deli and try a local delicacy called baby fingers. The deli existed, but "baby fingers" did not - the punchline was a breathlessly exclaimed "...it was a trick, there's no such thing as baby fingers and the guy thought I was a freak!"
Another constant source of hilarity at the band's live shows: Whenever They play "Snowball In Hell," John and John tend to improvise a routine (or record one in advance) in which they mercilessly lampoon the sample that appeared on the studio bridge.
"Did you say... what I think you just said — my hat looks good on me? I agree! I agree!" It makes an especially good Chew Out Fake Out because the song sort of dies down to create tension and then kicks back up again when it turns out the narrator is still happy. The music is being funny as well as the lyrics.
On the Amazon release of "Here Come The AB Cs," there is a re-recorded and re-worked version of their song "Hovering Sombrero" (originally of their "Mink Car" album). The original song is slow and relaxing. Their new version is fast, cacophonous, and only one original verse is kept. Every other lyric is replaced with Linnell, singing gibberish in a comically deep voice, and several overdubs of Flansburgh in the background shouting "B!" and "BO!" whenever the other John is silent.
Most of the in-between banter and discussion from the Frank O'Toole radio show on WFMU counts as this. It might be one of the silliest things ever recorded, and can be downloaded here
Special mention goes to the full version of "Doris Cunningham," as it was broadcast on the show. It's a clear example of the sort of humor that would later lead to such sketches as "Lesson No. 19" and "Turtle Songs of North America."
"We Just Go Nuts at Christmastime", the first song proper from the show, might be either this or a Tear Jerker:
Seems like only yesterday, our D-I-V-O-R-C-E, I love you both, but yuletide is still H-E-double-L for me
...but the spoken word on the bridge of this version qualifies it by a long shot
Flansburgh: Hi, this is John of They Might Be Giants, and you're listening to the Frank O'Toole radio show on WFMU. If you're driving your car now, we urge you to sit back, relax, close your eyes, and drive really fast.
"You're On Fire" is incredibly blasť, even though the narrator's telling the subject that their head is on fire.
As I'm sure you're aware You've got one of those rare Combustible heads I read an article all about them
The second verse is something to behold
No, you can't park there Whoa. Your head's on fire
From The Spine Surfs Alone, there's "Skullivan," a hilarious inversion of their usual take on Lyrical Dissonance. It feature's Flansburg's distorted voice wailing such lines as "I'll make you a pot of tea, how does everyone like their tea" and "I rented Tootsie, you gotta check this out" as Linnell chants the refrain over a tense, powerful instrumental.
The live version of "Hideaway Folk Family", as captured on the online-only release First Album Live, has them taking the Subliminal Seduction parody aspect of the "fake backwards" singing section a little further: Among the usual nonsense syllables are "Natas", "Yasmin Bleeth", and "Meryl Streep".
"Erase," the first Dial-A-Song exclusive featured once the service was reinstated, is a gleefully dark tune which includes such gems as:
Think of this as solving problems that should never have occurred Please don't call it strangulation, that is such an ugly word
