If Jim Carrey was suddenly declared God, what would he do? That's the premise, and only the easy, obvious routes are taken. But, as he did in Liar Liar, Carrey makes them funny even if you're determined he won't. Thus he enlarges Jennifer Aniston's breasts and you guffaw like a goon because the man is a comedy giant: you want him to fall on his ass, he does, you laugh again.
