every rose has its thorn

The above song title - listed on the back of Poison's Open Up and Say...Ahh! as "Every Rose Has It's Thorn" - has always stayed with me as the one of the most widely distributed grammar snafus I'd ever seen. This typo may not reach a comparable audience, but all I gotta say is ouch.

Note: I removed the link because the guy whose tattoo read "You bleed just to know your alive" blocked the photo. He was very sensitive about the fact that people didn't understand he wanted it that way. Maybe Poison can relate.
