You know life is bland when you take a butt-load of stolen cash and go to buy pizza...
Jesus, even I can afford pizza.  Although... the beer was probably worth more than the pizza.  That is, if he was getting a slice of pizza, and not a whole pizza.  
Actually, food prices have gone up.  Maybe the pizza slice was worth more.  Do you think they serve pizza in jail?  He could possibly steal another jail-mate's pizza and then act like he won.  Maybe.  Then again, he wouldn't have his beer.
Ah well, best not ponder it too much.
