Well, mine was from eons ago. when I used to walk around the house barefooted and someone could sneeze and I would stub, and thereby break or dislocate, a toe. My family and friends would always tease me and ask why I never wore shoes around the house. My initial response would be, because then I would have to tie the shoelaces and it's just a pain in the ass. Well, Mists of Pandaria came out for WoW and I figured why not throw a little flair into it. I made a Pandera monk (they have a special action in which they do a somersault roll) and I had a hotkey that would emote, 'Taimaishoo curses and exclaims as he trips over his shoelaces, "Oh! My shoe!"' as he would do the somersault roll.
