I've been worked on by docs and nurses that I saw socially when I worked at a real remote hospital. They were always very professional. Except... apparently when under anesthetic I suddenly remember every joke and stand up routine I've ever heard and start reciting them.
On slow days someone would invariably crack "Hey, let's give [me] some Versed and get some new jokes!" Or they'd say at a gathering "Tell the one about ___________." And I have no recollection.
