All I'm saying is, if you're going to fashion a costume that turns your head and its associated mouth into a ginormous key-hole, you better damn sure pray you don't ever meet the Keymaster:

"Hey, put that thing down ... no, seriously, that doesn't go in there, that's not a UUUURRRKRKKK!"
Bad, bad, bad choice there Mr. Key.
