Things that have tickled my thought lines lately:
–Do semi-trucks have rear-view mirrors?
–Why is it called “hamburger” when it is never made out of ham?
–Why is it that men take their business calls with them to the men’s room? (I have sort of first-hand knowledge of this since my office shares a common wall with the men’s room). I have not witnessed this same action from women.
–Do peacocks molt their tail feathers? (The one I saw several weeks ago is now “tail-less” … still roaming the same intersection).
