Catching Steve-O with his pants down probably wouldn’t come as a shock to most of his fans, but it’s what he’s dropping trou for this time that might catch some of them off guard.

The Jackass star shed not only his pants but every stitch of clothing he was wearing to star in not one, but two naked anti-fur public service announcements (PSAs) for peta2, bearing the taglines “Ink, Not Mink” and “I’d Rather Go Naked Than Wear Fur.”

Wearing nothing but his tats and a smile during his rooftop photo shoot, Steve-O told us that he’s never liked fur–and really, who could, considering that animals are drowned, gassed, strangled, beaten, electrocuted, and skinned alive just for “fashion”?

Spoken in true Steve-O style, he had this tip for all of you, “Abuse yourself all you want, just leave animals out of it. Don’t wear fur.” Watch the mayhem unfold in the exclusive behind-the-scenes footage of the making of Steve-O’s PSAs. We have to warn you though: You are about to see a totally naked Steve-O. (OK, he was totally naked, but thanks to the magic of editing: well, just watch it and see.)

Now take a cue from our buddy Steve-O and refuse to wear fur by signing the fur-free pledge below. You won’t be sorry–and just like Steve-O, millions of furry animals everywhere will jump for joy!
