After Bruce Willis tells Mary-Louise Parker that fans sometimes respond to him as if they've seen "an alligator fly out of a swamp and start singing Chuck Berry," Parker decides to prank Willis with an actual live alligator on the set of their movie 'Red,' she said on 'Live With Regis and Kelly' (weekdays, syndicated).

"So ... I managed to find an alligator and put it in his trailer and I put Chuck Berry on," Parker said. "Truthfully, it was more like a, kind of, bloated lizard. It wasn't very big."

"But where ... ? Do you just pack alligator typically with you?" asked Guy Fieri, clearly amazed that Parker was able to find an alligator in the first place.

"When you're a movie star, you're like, 'Listen, in my rider it clearly states I need an alligator,'" Kelly Ripa explained.
