One of our doctors made a mistake on one of his orders, so I took the chart over to him as he was walking out to leave and asked him to correct it. He asked me for a pen, and both me and the unit clerk handed him a pen at the same time. Now, our unit supplies us with pens, so they both were the exact same type of pen. I don't remember whose pen he actually used, but when he finished he handed one of the pens back to me and I said, "No, that's HERS (pointing to the UC), THAT one is mine" and gave the pen he'd handed me to the UC, and took the other one. He just looked really confused, poor guy. I was like "Um, I'm kidding." It's a bad joke when nobody laughs.
Another time the head doc of our podiatry unit came over to do a consult. Now, like most nurse's stations, we're short on chairs, so all the chairs were taken except one of those little plastic kiddy chairs, the kind that are about eight inches off the ground - I have no idea how it got there. Anyways, he comes over with his chart and I say, "Oh, we saved you a chair" and point to the little kiddy chair. Thankfully he had a good sense of humor, and laughed and actually did sit down in it, at which point I gave him my own chair. The other nurses looked rather shocked, though :imbar
Another time someone had left a set of keys on the counter, along with a condom and a packet of lubricant. No one knew whose they were, but we made a point of asking every doctor who walked by, really innocently, "Are those your keys?" You should have seen the looks we got. Finally our unit manager overheard us and threw the whole pile away.
