"Sweetie, I get the feeling your father has been a little impatient for us to have a boy."
"Why do you say that, hon?"
"Oh, you know, all the baseball equipment for the girls' birthdays..."
"They loved those!"
"And the football helmets..."
"Once we painted the tiaras on they wore them all day."
"And you know earlier, when we told him we were having a boy this time? I'm sure that back flip couldn't have been good for his arthritis."
"Oh, he was just being cute, is all. I'm sure the thought of us having a boy is no more exciting for him than the thought of our having another girl."
"Riiight. Have you seen the cake?"
"He bought a cake?"
"Er. Does he think we're naming the baby Finaly?"
"That's supposed to say 'finally', dear."
"So, do you want to tell him we were joking, or shall I?"
Amy W., I'd wait 'til after the cake was served.
