I have vivid memories of a cartoon with signs pointing "this-a-way", "that-a-way", and "a-weem-a-way", which I think come from a goofy Paranoia sourcebook.

I put a mutant version of the "in the jungle" tune in 8.xm. It also includes a snippet of a Hungarian musical my roommate was constantly listening to at the time. True story. I'll shut up now.

I wonder whether Ken Jennings is a wikipedia junkie? He has to get his general knowledge somewhere, and encyclopedias seem like the second most likely choice after Bargain With Satan.
