That's so cute. I can see Tank being all "I can't believe I'm effin' pregnant!" in front of other people, but then he secretly loves it when they're not around.

I love when they rub their stomach like that. I remember all Circe did was rub her aching back and look angry. She was an amusingly hostile pregnant woman.

Hey, it's a good idea to excercise while pregnant. I'm not surprised that Tank found something low-impact that he could do to keep fit. :P
