Olivia Wilde's stripper character in the outrageous comedy Butter is supposed to be more funny than sexy -- but she still busts out some pretty impressive moves on the pole. And what's more impressive? The actress only had two days to train for her naughty performance! "We had a great trainer fly down to Louisiana to work with me," Wilde told iVillage. "She tried to teach me things at the local strip club...and then I hung out with the real strippers there and they were all so sweet. I'm really genuinely impressed by their skills."
