Todd, you’re flat!

I can’t take credit for this joke. It was from a bit me and my daughter were doing in the car. For some reason we were pretending to be singing frogs. I made a couple frog noises, then she made one that was a straight up “ribbit” then quickly switched character voices to the frog in charge and said “Todd, you’re flat!”.

Not sure what’s funnier. The idea that a frog could be out of tune. Or that the frog’s name is Todd.
