If I recall, they were visiting an actual website where one's personality can be tagged to a sushi dish like the blood-type mythology Japanese love so much.
I've no clue what kind of exotic sushi had poisonous claws but if you browse the episode thread, I vaguely recall someone discussing it there.
The Tommy Lee cameo was also noted in the associated episode thread -- he was the spokesperson for a sequence of commercials in Japan at the time. If you've seen Bill Murray's movie "Lost in Translation" (whisky spokesman), it parodied that sort of thing. And in real-life a sequence of drink commercials featuring Governor Arnold S. screaming at you from inside a bottle can be found on youtube.
Don't remember the sleeve incident at the moment to comment.
No, this is a fine spot for these sorts of questions as long as they're bundled up like that.
But unlike a lot of anime threads here -- the episode threads actually have a fair amount of cultural reference, gag explanation, or trivia bits stocked up in them.
