Doug Melvin's Evil Twins on Biggest Loser?

This is pretty off-topic seeing as there is a pretty huge Packer game in a few days, but I happened across "The Biggest Loser" last night, and this was too funny. Either Doug Melvin has multiplied with himself and got really, really fat, or he is 1/3 of a set of triplets, two of which have different last names. And if it wasn't for the Biggest Loser t-shirts, I bet you couldn't tell me which one was Doug Melvin. Tell me I'm wrong.
