I definitely overheard this conversation between two doctors today:
“That was fast”
“That’s what my wife says. “
“Hm?”
“My wife doesn’t actually say that. It’s a joke. Kind of like ‘that’s what she said’.”
*muddled expression* “Oh. . .”
The adorable little Type A nerds might be able to save your life, but they probably aren’t going to pick up on social cues.
p.s.
How cool?

I also love that he was making the joke at his own expense.
