When Rolling Stone unveiled their latest cover featuring the stars of Mad Men, it didn't take long for Jezebel to spot at least six Photoshop failures. Plus, Jon Hamm looks like he's having a difficult bowel movement, so that's pretty great.

Rolling Stone has a nice gallery of arty on-set shots from Mad Men. Lots of nice eyewear (and really beautiful people.)
