Ozzy OsbourneOzzy Osbourne has been forced to choose between sanity and sex: his anti-depressants prevent Viagra from working.

“I can’t do it. I’m on anti-depressants. I take four Viagra and it doesn’t work - it doesn’t do anything!” he revealed recently.

But he can’t give up on one for the other: “If I get off anti-depressants, I go mad.”

“When you first have a relationship, you’re like rabbits. We’ve done it so many times, it’s f**king boring,” he added.
