Spelling "Mommy"

Nolan was playing with some alphabet cutouts (which only contain one of each letter) when he hollered over to me, "Mommy, I need another 'M'. I only have one!"

So I said, "Why don't you just turn the 'W' upside down."

A few seconds later he called me over and said, "Look, I spelled 'mommy'! And I turned the 'U' upside down to make another 'M', too!"
