Why Are You Under There?

So This afternoon when I picked up Aurora from school. She had a funny joke to tell me.

Aurora: Hey Mom I have a joke for you.
Me: Shoot!

Aurora: Why are you under there?
Me: ?????
Me: Under Where?

Aurora: HA..HA... You said Underwear...

Me: Nice!

SO there I have fallen for the most RE-DONCONLUS joke ever!!!
