A man walks up to a janitor
-
A man walks up to a janitor and asks him, "Don't you ever get tired of cleaning."
The man, taken back, says, "Excuse me sir. I'll let you know I have children at Harvard, Yale, and MIT."
The other man replies, "Oh really? I'm sorry, what classes are they taking?"
The janitor replies, "Nah, they're janitors."
