Seen here looking like a male Tina Belcher, Redditor THE_UPDATE_UPDATER displays his Halloween costume. He's an avocado. His belly is the seed. Remember when you were a kid and you were scared that if you ate a fruit seed then that kind of plant would grow inside your stomach? You were so dumb back then. Except for the seed thing, that's a legitimate concern.
Thanks to Elizabeth, who pointed out this is a great costume for pregnant women and men with beer bellies. I'd do it, but my bellybutton is on the side of my stomach and I'm embarrassed about it
