Thats not a punchline, dude
You seem to be going for absurd sort of humor in this piece, one problem theirs a difference between absurd and random. The idea of any character meeting a fan is an absurd idea and can lead to lots of good jokes, but eating them is not one of those jokes, did you pull the idea for the ending out of a hat, you might as well of had him call the pope to beat her with a bat.
