The comic actor - who stars alongside John C. Reilly in new movie "Step Brothers" - admits he can't help snacking on the frozen treat while emptying his bowels.
He said: "I like to eat a pint of ice cream on the toilet!"
Will recently revealed the fake genitals he wears in one scene in "Step Brothers" were modeled on his own testicles.
He said: "They are not real but my balls were modeled. I put them in hot wax to build the mold."
"I asked the prop people, 'Could I please have my stunt nuts to take as gift from the movie?' and they said, 'No
problem.' So they're at home."
"They've been brought out on a few occasions - we had a dinner party and the subject of the stunt balls came up and I went, 'I have them, do you want to see them?' They got passed around by 20 people!"
