The last cocktail in the last show: A Modern Britain. Stephen starts with Patriotic Fervor over the ingredients: Jersey cream, Islay malt whiskey "lovingly blended by craftsmen who care," garnished with a shamrock, a thistle, and a rose before moving onto the "modern" ingredients—flat cola, low-calorie sweeteners, a two-parent family-sized back of diluted good values, etc... while Laurie and the guests mournfully lower a British flag and Robert Dawes plays a solemn song on the trumpet. Stephen mixes the cocktail by sobbing "It's ruined! BRITAIN IS RUINED!" and wringing out the handkerchief into the mixture while Hugh tries not to laugh.
"The product shall be half-baked in an immoderate temperature of the Lowest Common Denominator in an atmosphere of greasy cant and corrupt sleaze, until richly dishonored and seared with shame. Your Modern Britain will ideally by now have lost all color, flavor, and fizz, and should be then divided against itself and left in shoddy disrepair for a number of years, until it rots before being sold off to the highest bidder."
The "Tony of Plymouth" sketch. A typical corrupt MP (Stephen) giving a speech, heckled by a man (Hugh) who appears to have been Born in the Wrong Century and heckling him with phrases out of a Robin Hood legend... until Stephen responds in kind and the heckler reveals himself as the famed Tony of Plymouth and swings onto the stage in true swashbuckling fashion. Stephen is outraged and steps away from the podiums, revealing that he's wearing bright yellow hose and a rapier below the suit jacket. Cue the Flynning.
Politician: And what is your name, sir, who must shroud yourself under a light traveling cap? Tony: My name, sir, and I bid you mark it well, is Tony of Plymouth!
When the Nazi Fredrich von Stoltz (Hugh) turns to do some dramatic pacing, his British prisoner Donaldson yells out "GET THAT ARSE!" Stoltz, who's already unnerved by Donaldson flirting with him, jumps about a foot.
The "Kickin' Ass" song. Between Hugh's thick twang to Fry's shouting "KICKIN' ASS!", the song is a hoot.
The broad Scottish nan accent Stephen's host character speaks in.
Hugh's interview with "Michael Jackson," satirizing Jackson's infamously drastic appearance change, which was just beginning around this time. It's just Stephen looking, sounding and acting like his complete normal self. No costume, no makeup, no changed voice.
"Michael"'s excuse for his drastically changed appearance when compared to a stock photo of him from the '60s?
