That one is hard to beat! Glad the guy didn't have a stroke.
Here's one that's close, though decidedly more bloody.
When i was 12 I was fishing with my uncles. We saw this little old lady who was down at her own part of the lake fishing with an old-fashioned cane pole - a long stick with a thick line tied to the end. No reel or anything.
Anyway we didn't even notice her until she caught a fish and dragged it to land. It was a Northern Pike, about 3 feet long with a long narrow mouth filled with teeth that are truly razor sharp without exaggeration or dramatic license.
Anyway, she had tried to get the hook from its mouth and it bit her, she was bleeding. As one of my uncles went back to get a pair of needle nose pliers, this guy who sounded like he was from somewhere in the Eastern Europe area who was also fishing nearby ran over to help her out first. He picked up the pike by its gills (which is how you are supposed to grab a pike, as it mostly paralyzes them from the grip and they won't flop around). He then reached his finger into its mouth, very deep. The fish was not THAT paralyzed! It chomped down on his finger and the guy pulled his hand away as fast as he could. His finger came out of the pike's mouth without a bit of skin left on it. This is about 1988, so we had to find a payphone and call 911. The ambulance came and took the guy to the hospital and gave the little old lady a bandaid for her relatively small bite. We helped get the hook from the fish's mouth using needle nose pliers.
I also caught my first largemouth bass and got the worst sunburn I've ever had. But that's better than the guy who had to go to the hospital.
