Dad and Cash

"Dad you better slow down, or the speed lemon is going to catch up! And you will go to jail"

"I won't go to jail."

"Yes sir dad, it's against the law, and the speed lemon will get you"

"Yes it is against the law but you don't go to jail, you get a speeding ticket."

"Why don't you go to jail?"

"Because it's not bad enough to go to jail."

"....is it good enough?"
