The Leaky Pipe.

JoeI took Joe to the bathroom so that he could do a “stand up job”. I have to hold him up so that he doesn’t fall during the process, and when I didn’t hear anymore tinkle sounds I asked him if he was all finished.

Joe:  “It seems like it’s done draining, as far as I can tell…”

About the time he finished his sentence, I heard some more tinkle sounds.

Joe:  “Whoops!  Looks like we’ve got a leaky pipe!”
