My turn last night / this morning. This is number 3 for me.
Didn't find anything of interest. No lost keys. No 10mm sockets.
As I'm waiting in the prep room for my turn, I found out I was too close to the procedure room. Some guy must have woke up during his procedure.
"Linden! Linden! Stop fighting us. You need to turn back on your side. You're having a colonoscopy!" I heard this several times, then "If you don't turn back on your side, we're going to have to stop and this all over again." The doc must have given up, as I could kind of hear them talking later, but I couldn't make out everything. Seems he's an alcoholic, and the booze has made him somewhat immune to the propofol.
