Making an X

A friend posted this Facebook status, with responses.

I. wonders what made her twin boys think it would be a good idea to go in the front door (upon arriving home from MDO), through the house, out the back door, and then pee on the deck - at the same time. A tree would be ok, I guess, but the deck? Sigh.

That's just a boy for ya! At least it WAS outside....

True, G.! What's even funnier is when they think they must go at the same time (in the same potty) inside and laugh hysterically because, in their words, ..."We made a X!!"
