O.J. Simpson has been busted in a prison cafeteria cookie caper.

Prison guards in Nevada caught Simpson in his cell with a dozen cookies hidden under his shirt.

Simpson is serving 33-year sentence for armed robbery.

The 66 year-old NFL Hall of Famer reportedly was given a warning for the half-baked crime and was told to keep his hand out of the cookie jar.

To me, it seems like it's always the ones that you would least suspect.
