We saw his backside in “Old School,” but this time funnyman Will Ferrell is showing some skin for a good cause. 

Ferrell is pitching a line of SPF 30 sunscreen products on Amazon, eBay and www.cancerforcollege.com for $11.99. Sales will fund scholarships for cancer survivors and amputees through the non-profit Cancer for College.

On each bottle, Ferrell strikes a pose. On the “Sexy Hot Tan” line, Ferrell bares a bit of his bum a la Coppertone Water Babies. On ”Forbidden Fruit,” he daintily covers himself with a leafy branch and smiles impishly. And the actor sports a hunky dark tan and grasps a golf club on “Sun Stroke” and says, ”I added 57 yards and a rich, dark tan!”

Jokes aside (because we all know Ferrell can be funny), it does show a more serious side to the former “Saturday Night Live” star, whose new comedy flick “Land of the Lost” debuts in theaters this week. He met the charity’s founder and two-time cancer survivor Craig Pollard during their college days at University of Southern California. Ferrell has been a long-time supporter of the charity, hosting fundraising events since 2002.
