This guy has been working as a bag boy in a supermarket for 5 years. One day the supermarket gets new orange juice machines, and the bag boy is real excited and asks the manager if he can work the juice machines. The manager says no.

The bag boy goes, “But I’ve been working here for 5 years, why can’t I run the juice machines?”

The manager goes, “I’m sorry, but baggers can’t be juicers.”
