Meow

Me: "Hey, guess what my physical therapist makes me do when he catches me standing with my hip out."
S: "Meow?"
Me: "Um. No."
S, snorting and cracking himself up while mimicking my physical therapist: " 'Now, every time you stand improperly you must give me one meow.' "
S, mimicking my reply to my physical therapist: " 'Well, OK, but I don't see what it has to do with my therapy.' "
S, mimicking me mimicking a tiny sweet kitten: " 'Meoooww.' "
S, doubling over with laughter while still mimicking me: " 'Mmmmmeeeooooowwww.' "
Me: "Nope, that's not it."
S, wiping away laughter-tears: "OK. So what does he make you do?"
Me: "He makes me squeeze my butt cheeks together ten times."
S: "Ahhh."
