Underduck! Reminds me...
I got tired of "underdogs" one day and told my daughter "Now it's time for an under-cow!....Moo, moo, moo!" Then she wanted an under-cat, and under-pig, an under-donkey, an under-elephant... complete with animal noises.

Finally she got a mischievous look on her face and said "Now do an under-parent!"

I took a deep breath, and as I ran under the swing I shouted "Do your homework! Brush your teeth! Go to bed! Young lady, what do you think you're wearing?!?"

As I released my daughter at the top of the arc, I noticed an elderly lady near the merry-go-round listening. She started laughing so hard she almost cried.
