Do you remember the exact moment when you told your husband (or boyfriend or whoever) that you were pregnant? What am I saying? Of course you do.
I'm sure his reaction is permanently stuck in your brain, regardless of whether he was elated, annoyed, or totally scared to death.
But no matter what emotion he expressed to you after hearing the news that you had a bun in the oven -- you gotta wonder what, exactly, must have been going through his brain right afterward.
