I like playing halflings and gnomes because they need to have long, silly names. My gnome locksmith/exterminator (he was a poor honest businessman who learned rogue skills like trapmaking, lockpicking, etc.) had the name Bayleyburgle Fiddlewick. The name isn't particularly belly-busting funny, but after awhile other players started massacring the name just for fun..."Okay, Baleybiddlebarleybagel, what'ya doing?" And my group is particularly merciful considering what you can attempt to rhyme with Fiddlewick.
