I know we're not supposed to be mean on here, but Steven is so despicable. He had NO success on the show, but I have an idea.
Put the rude jerk (naked) into a high-walled kiddie pool with a drain that leads to the sewer system. He can poop and pee in there, and the flushing system is a shower of soapy water, then a rinse.
At breakfast time, you toss him a head of iceberg lettuce. At lunchtime, a bag of carrots. For dinner, if he hasn't been himself a complete asshat he can have a grilled or baked chicken breast. For a snack, a container of no-fat Greek yogurt or tablespoon of peanut butter Oh, and the room's soundproof. We'll keep this routine for 6 months, then have a weigh-in.
THEN we'll see what's what.
