Blake in the car: "I have to go to the bathroom."
Me: "Well, you'll have to hold it."
Blake (in whiny voice): "But I reeeeeally have to go!"
Drew: "Well maybe you could come up here, open the window, pull down your pants and go pee out the window."
Both of them giggle.
My husband: "And if you do that, you'll both be cleaning the car when you get home."
A few seconds later.
Blake: "Drew, THAT was a toootally awesome idea."
More giggling.
