Big Bums

I just had a "most embarrassing moment" today. We were walking out of the post office and Joey was standing right in the door way. Two (large) people came walking up behind him and I said, "Joey move out of the way." He looks up and moves over to the side and the two people start walking out. Joey turns and says to me (in a not very quiet voice), "Mom, they have big bums."

HOLY COW!! Please tell me what you would do in this situation - besides wanting to die of embarrassment (I already did that).
