I was flying transatlantic with a friend who has a medical degree when they called for a doctor. There was an older fellow who had a heart condition for which he was taking medication. His reasoning had gone something like "I need to take one of these pills four times a day, but I'll be traveling, so I'll just take all four of them right before checking in". Needless to say, this didn't work very well, and he was having sort of issue with his heart as a result. The poor guy was so scared he literally shit himself. My friend actually had to make the call whether we needed to land on an airport in Greenland to get the guy to a hospital. He thought about it for a minute and decided that the guy was going to live, so we continued to Amsterdam, where an ambulance was waiting. As a "thank you" from KLM, my friend was allowed in the cockpit during landing (this was before 9/11), and he got a bag full of little bottles of alchoholic beverages. Unfortunately, he's a teetotaller.
