Kirstie Alley Compared to Pig by George Lopez (Video)

The TBS comedy host skewers a number of "Dancing With the Stars" contestants.

George Lopez skewered a number of Dancing With the Stars contestants on his TBS late-night show this week.

He joked that Playboy playmate Kendra Wilkinson calmed herself down before performing by "picturing the audience picturing her naked." He also mocked her relationship with Hugh Hefner, many years her senior.

Ralph Macchio, best known for playing Karate Kid, "cut a mean rug, then took the rug he cut and glued it to his head," Lopez quipped.

Lopez called Wendy Williams a man, and said she danced like she had toilet paper stuck to her feet.

But he saved the nastiest jokes for Kirstie Alley (who was praised for her cha cha cha to Cee Lo Green's "Forget You" with partner Maskim Chmerkovskiy) by comparing her to a pig.

"She did a nice job, her little hooves tapping away. Before the show, she went to the market, and then she had roast beef and this is her going all the way home!" he said, before cutting to a squealing pig from a Geico commercial. Watch above.
