Random man in the aisle: That a boy?
Husband and I: ?
Me (after realizing he was referring to my pregnant belly): Oh. Yes! We are having a boy!
Man: Yeah. Thought so. Hmm. I think he is going to be born on a famous person's birthday.
Me: Oh yeah? Hmm. We'll see. (smiling and thinking "Isn't that EVERY DAY?!")
Man: Yep. And I think (tilts head)...I think he may be a scientist.
Me: Oh! Wow! Maybe so...
Man (as husband and I scurry away): Hope you're listening to lots of classical music!
