(Disclaimer: I don't recall how this conversation started. It's possible WinnieTheWoot asked the initial question simply to relieve the boredom.)
WinnieTheWoot: Are you a unicorn?
Me: (rubbing my NON-POINTY forehead) Um, no. I don't have a horn.
WtW: Maybe your parents had it cut off when you were little.
Me: And it didn't grow back?
Me: Like a foreskin.
WtW: What is wrong with you?
