Chez Goodman has compiled a list of "doin' it" funnies. Many here I have never seen before and some quite good, such as "Non-smokers do it without huffing and puffing." Unfortunately, the ones for nurses are not very good:
Nurses do it with aseptic technique.
Nurses do it with fluid restriction.
Nurses are prepared to resuscitate.
Not very good, but still funnier, I think. And, of course...
Nurses do it as the doctor ordered.
Nurses do it to patients.
That's all for me, folks. Thanks, you've been great. Goodnight.
