Headaches.

John and I were talking about how cute Kaleb is last night and the rest of our conversation went something like this:

Me: I can see why people have ten kids.
John: (Silent for a moment.) I have a headache.
Me: (Dying of laughter.)
John: No seriously, I just got a headache. I don't know if it is because you said that or if I was already getting it.
Me: Don't worry, I don't want ten kids... I can just see why people have really large families.
John: Okay, we should probably go to bed now.

I am sitting here laughing just thinking the look on his face.  :)
