Can anyone point me to the rules of the word game "Botticelli?"

It involves taking a word, making a pun on it, and having the next person pun on that (I think).
For example, borrowing from goodgold's thread:

Rodomontade? Isn't that a French dish on wheels? (i.e. roulade)

I've always wanted to know how to play this game, and have only heard references to it.

what is it about this guy and his eponymous games? is it
all just because he played a shell game with the Medici
family? there is B for Botticelli, a great family travel
game (of which Pynchon had the characters in one of his
books playing a 'strip' version); there is Botticelli,
another quiz game where the name is used for scoring (sort
of like in H-O-R-S-E); and now a punning version, with
which I am not familiar.

but wait, college kids love to pun and probably play B for
Botticelli with all kinds of twisted rules.

anyway, here are a couple of links, one with the basic
family version and the second a transcript of a Swarthmore
radio call-in version; you be the judge.
