my jaw dropped open

Overheard at work:

"I'm feeling better today. Maybe I won't be as nasty to be around."

"Oh really? That's good."

"I have yet to get a good night's sleep though. I seem to have a hard time falling asleep."

"Gosh, that's not my problem. I just can't stay asleep. I feel like I wake up 10 times a night."

"Oh by the way, how are your husband's testicles?"
