Wisdom by the Slice

Our local pizzeria features a buffet. Actual conversation:

Mike: (Examining the meaty pizzas on the serving bar.) Excuse me, sir, are there any veggie items here? I'm a vegetarian.
Manager: (Strolls over.) You're a vegetarian.
Mike: Yes.
Manager: (Glimpses and touches several pizzas.) So, what do you eat?
Mike: I eat nothing with meat.

Long pause as the manager contemplates his various pizzas on display.

Manager: (Eyes light up.) Do you eat bacon?
Mike: Um, bacon ... is ... a ... pig.
Manager: Bacon. You don't eat pigs....
