'Extra' Raw! Margaret Cho Shows Mario Her 'DWTS' Moves

"Dancing with the Stars" contestant Margaret Cho joined "Extra's" Mario Lopez at the Grove -- and admitted she wants to plump-up the competition.

"I'm about 50 pounds larger," joked the comedian. "I'm like two Jennifer Greys. I'm like three Brandys. I'm like four-and-a-half Audrina Patridges. I'll dance naked, it doesn't matter."

Watch Cho go with Mario!

The "DWTS" rehearsals for opening night are almost over... the showdown begins Monday, Sept. 20 on ABC.
