Science, ancient history, all types of art, animals, natural environments (with indoor plumbing preferably), and most types of comedy. I love to laugh be it cerebral or slap stick
Anyone who has a good sense of humor (but who isn't a total nut. I've got enough of them in my life already).
Bryan Adams, Great Big Sea, Bare Naked Ladies and anything I can sing along to. Christmas music works well any time of year. (The Wiggles aren't bad either)
Gotta be comedy, especially dark comedies or slap stick, Mel Brooks stuff, and some sci-fi
All Star Trek, Boston Legal, Scrubs, The Office, The Daily Show, Father Ted, x-files, Get Smart...
Clan of the Cave Bear, anything by Colleen McColough, The Hitchhikers Guide to the Galaxy, Tom Robinson.
David Suzuki, Steve Irwin, Gene Roddenberry
