A buddy of mine told me he was in a public restroom the other day. A father was in one of the stalls with his obviously young son. The son was chattering on about this and that. The father was becoming more and more impatient and said to his son, "Why don't you just take care of your business?"
"Your business, you know go to the bathroom."
The son replied with wonder in his voice, "You mean you're gonna pay me for this?!"
