How many times can you use the word "and" in a row in a sentence and have it still make grammatical sense (once you wrap your mind around it)?

So a worker was painting a sign outside a building. The boss came out and read it "Ampersand&Anderson" and told the worker "No no no, that's all wrong. You need a space between Ampers and and and and and and and and and And and And and derson."

Ampers and & And erson

heh.
