"I Lose," a very short play in one act

Felix:  "Hey mama?"
Felix:  "Hey dada?"
Me:  "Why'd you say 'mama'?"
Felix:  "Don't say 'why'!"
Me:  "OK.  What?"
Felix:  "What?"
Me:  "Yes, what?"
Felix:  "Why did you say 'what'?"
Me: "You said, 'Hey dada.'"
Felix:  "No I didn't, I said 'Hey mama.'"

I lose.
