"Hah!  I have 29!"
"Oh yeah?  Well, I have 19, see?"
"That's impossible and you know it."
"But I have it!  See?"
"...dear lord!  You really do have 19!  Wait, what game are we playing?"
"You don't know?!  Whack-a-mole, obviously!  Pay attention!"
"Say, isn't that Marvin?"
"Yes, I am Marvin, the star-nosed mole, and I want to buy a brown car."
"Sorry, duddes, but the game's called whack-a-mole, so..."
*bonk*
"Ouch."
"Don't whack this mole, or you're under arrest."
But Marvin got whacked again.  So the police showed up and arrested
everyone in sight.
