George Clooney's Problem (But Don't Feel Sorry for Him!)

Romantic Twitter posts from current girlfriend Stacy Keibler seem like they might disturb the 50-year-old actor's status quo, but as he tells Rolling Stone, it doesn't bother him.

"She can do whatever she wants," he says. "I rarely tell anybody what they should be doing with their life."

In fact, not much seems to bother Clooney. When asked about the box office returns for his latest film, the political thriller Ides of March, he says it was made for a smaller audience.

"It's not designed for everybody to see, but I don't give a s---," he says. "I don't need to be more famous and we shot it for $12 million, so anything we do is nice."

That means he should be pleased with March. The film, which he directed, starred in and co-wrote, has grossed just under $40 million, domestically, after a month in theaters.

The interview goes into stranger territory when it turns to his less sophisticated sense of humor. Clooney, a notorious prankster on sets, waxes poetic about the humor he finds in farts -- real, fake and theoretical.

"We think it's one of the funniest things in the history of mankind. Even the idea of a fart makes me laugh," he tells the magazine. "Saying the word 'fart' makes me laugh. I have iFart on my phone. I have remote whoopee cushions. Farts. To me, there's nothing funnier."
