Actual conversation today. My wife: "i'm tired of anaesthesiology. What other area of medicine should I try?"

Me: I don't know. Emerg? Wife: Nah, I want something lower stress. Hey, what about sleep medicine? Me: Sleep medicine? Wife: Like, helping people with sleep disorders and such. I wonder what sort of education i'd need? Me: Probably night school.

edit: yes, I know it's an awful dad joke, but it happened on the fly and its the greatest thing i've ever accomplished, so please, let me have it.
