Appearing on The Late Show with Stephen Colbert to promote his new Netflix series, Living with Yourself, Rudd was quizzed on his workout and diet regime while preparing for Marvel's Ant-Man. However, unlike other super hero flicks, Rudd doesn't actually strip down.
Colbert asked why that was the case and whether Rudd had ever "done full nude professionally."
Well turns out he has got his junk out before, but unintentionally. In a play with Rachel Weisz, Rudd found himself lying in bed with the actress in just boxers. Much to Rudd's confusion, onlookers started chuckling. He soon realised his leg was up and he was "totally hanging brain."
Rudd quickly clarifies that "hanging brain is not so much the penis hanging out but more of the testicles."
Wonder if he's ageless down there as well...
