The Couch Problem
The family is sitting in the living room when Dad flops down on the couch.
“Dad, why are your clothes so dirty?” his daughter asks.
He sighs, “Because I just fixed the drain under the sink, and let me tell you, it was gross down there!”
His wife says, “How gross?”
Dad grins, “Let’s just say, if the drain could talk, it’d have some stories dirtier than me!”
