I also got them all, but I've heard #2, #3, #5, and variants on #1 before, so they were no challenge. :) These puzzles are sometimes called 'lateral thinking' puzzles. I'm fond of them, but I like them to be mixed with a little traditional problem-solving skill as well. The 'aha' books by Martin Gardner are full of puzzles that strike just the right balance.
