Trivia:

• Discretion Guaranteed is written in huge letters on the side of the photography van.
• Dr Hibbert is originally from Alabama, and Springfield is 299th on the list of America's most desirable cities, just below Dawson's Creek.
• Springfield has eight malls, 32 bars and 13 stores that begin with 'Le Sex'.
• It has no alternative theatre, no symphonies, and the library's reference department has been replaced by an air hockey table and a make-your-own coffee bar.
• On TV, Homer watches Ethnic Mismatch Comedy Series #644 (which is full of Viagra jokes, much to Marge's amusement), repeats of the Princess of Wales's funeral, and a show called How Low Will You Go, sponsored by Grandma Plopwell's Pudding. Homer takes part, obviously.
• He wears a suit made of popcorn, Bart dresses as Bartman, Barney drinks a six-pack in one go (he actually intended to juggle chickens), and Moe is going to sing like Shirley Temple.
• Others lined up to do their acts include Mr Burns and Smithers as a pantomime horse, Kirk van Houten as a baby, Apu as a holy cow, and Lenny comes dressed as a urinal!
• Homer poses in the house to I'm Too Sexy, an inexplicable 1991 hit for Right Said Fred.

Notes for Brits: Madeleine Albright, seen here judging the contest, was the current US Secretary of State.

Look out for: Bart riding naked on a wild hog. Later it is riding him!

Notes: It is Stephen Hawking's cameo that saves this retread of Lisa the Simpson from being very boring. Once we're past the How Low Will You Go show, the episode takes a nose-dive until the last few minutes. Very, very tedious.
