Dane Cook Reveals the 'Dumbest Thing' Jessica Simpson's Ever Said

Dane Cook must be lactose intolerant because in a cheesy twist on Watch What Happens' game of "Plead the Fifth" -- CNN anchor Candy Crowley was asked to squirt canned cheese in Cook's mouth if he refused to answer a question -- the comedian answered every single question, even calling out his female co-stars.

When asked who his worst on-screen kiss was, Cook didn't hold back from calling out Kate Hudson. "I did a movie with her called My Best Friend’s Girl (2008)," he recalls. "I think she purposely ate like a feast of onions before our scene."

Cook threw a bit of shade on his ex and former on-screen co-star Jessica Simpson. Host Andy Cohen asked the funnyman, "You starred in Employee of the Month (2006) with Jessica Simpson. What was the dumbest thing you heard her say on set?"

Not even considering pleading the fifth, Cook answered, "She said one day, 'Are we making a movie?'"

Simpson and Cook seem to be friendly following their brief fling. Back in 2010, upon hearing about Simpson's engagement, the comedian congratulated his ex, telling Us Weekly, "Jessica's a great friend of mine and I'm so happy for her! She's an incredible person."

Four years and two kids later, Simpson tied the knot with her guy Eric Johnson over the summer. ET has an inside look into her lavish wedding:

Cook had one more confession to make before the game ended. When asked how many comedy groupies he's been with, the 42-year-old confessed, "In my younger days, I would say a few hundred."
