I heard about this yesterday. It's okay to bash each other with frying pans, but smoking would send the wrong message. Besides, who cares if Tom smokes? He's the bad guy, remember? And everybody knows that cats are EEEEE-VIL (except for Walt Disney, in most of his/their movies).
Tom's the bad guy? We always root for Tom. Although, I'm thinking our cat should stop watching Tom and Jerry, since she tries to play with mice (even invites them in) instead of actually killing them.
