Jack Nicholson has claimed that he takes Viagra to maintain his stamina during threesomes. (Brain Bleach!)

The seventy year old Oscar winner, who claims to have banged over 2,000 women, told The Guardian: “I like to date a nice range of women each year, but I only use Viagra when I am with more than one.”

“Sometimes I think to myself, ‘Well, Jack, you have met a lot of people over the years, there might just be some interest out there in you recalling some of them.’ But it would be a bit like taking a picture of the Grand Canyon, it would get in the way of being there.”
