O.J. Simpson got caught with his hand in the cookie jar, literally.

A few days ago the former Buffalo Bills Hall of Fame Running Back was heading back to his cell after lunch when the guard notices a "bulge" under his shirt.

Immediately the guards searched Simpson to find he was sneaking no drugs, cell phone or weapons, but a dozen oatmeal cookies from the prison cafeteria.

According to a source inside the Nevada prison where Simpson is held when guards found the cookies they let Simpson off with a warning and sent him back to his cell.

"O.J. just stood there with a goofy grin on his face as the guard kept digging inside his shirt and throwing cookies on the floor," the source told The Daily Mail. "So when the guards started pulling cookies out of his shirt, the other inmates just started laughing so hard they nearly fell over."

The former football star is in prison for his role in the 2007 armed robbery in Las Vegas. Simpson was sentenced to prison for 33 years after his trial in 2008 where he was found guilty.

Simpson is also believed to be involved in the murder of his wife Nicole Brown Simpson and Ronald Goldman in 1994. During the trial the jury found him not guilty and cleared him of all charges.
