Watch this video. See if you notice any disgusting, childish things going on.
No? Did you watch David Spade?! If not, watch again.
He takes his gum out of his mouth, and puts it right under the seat! WOOPS! YOU'RE ON CANDID CAMERA!!
That's gross... But watch that gum be on eBay later today. Except.. He's not as huge as he used to be, I guess.
Still... Gross. And so very, very hilarious.
