"On a flight from Moscow to JFK, a passenger asked for a blood pressure cuff. He had just received (as in, within the last 48 hours) a black-market kidney transplant in Russia and asked if we could monitor his vitals on the flight home. Fortunately, we had a nurse in our crew."
"A passenger asked for a Tylenol because her husband was in a bit of pain. He had a penile implant, his body rejected it, and, well, she pulled it out mid-flight."
"Once a passenger who, let's just say, probably should have bought two seats stepped on a piece of glass while on board -- barefooted. He asked one of the FAs to pull the glass out for him, because he couldn't reach it."
"One passenger asked for anti-gas medication. For the person in front of them."
