Yes, I'm Surrounded By BOYS

In the car on the way home from the beach, we had quite a serenade from the back seat:

Matthew blowing raspberries.
Brandon: Mom! He's spitting!
Matthew blows more raspberries and pretends they are coming from his diaper area.
Brandon: Ha ha! I can do that, too! Imitates his brother.
Mom: That's gross, boys, stop.
Raspberries in stereo coming from the backseat.
Mom: I mean it. Not funny.
Laughter coming from the backseat.
