Ryan Dunn, Steve-O, Johnny Knoxville & Bam Margera: A Tattoo Odyssey (PHOTOS)

The merry pranksters of the "Jackass" crew have made us laugh for almost a dozen years.

Constantly placing themselves in danger for our amusement, Johnny Knoxville, Ryan Dunn, Steve-O, Bam Margera et al, turn their bodies into canvases of the daring and the absurd and add indelible ink that lets the world know who and exactly what they are ― fearless dudes on a mission living life balls out!

There are too many tats to list, but the ones that definitely caught our attention belonged to loveable Steve-O who has a tattoo of himself on his back and Bam Margera.

Steve's message was simple: he's got his own back!

After the break, check out some of our favorite "Jackass" tattoos!
