Nothing anywhere near most of the folks on the video.
Worst day on the ice: Red Lake, ice-roads had melted and re-froze earlier in the week. Dropped the front of the pickup into a slush-pocket. Dug a bit, got yanked out finally, broke the connector between the upper and lower control arms on the passenger-side front. It was inconvenient, but not really dangerous.
Worst day in the boat: 1st day actually fishing in my brand new (at the time) 1850 Crestliner Fish Hawk. While putting in the electronics myself, I'd pulled the rear deck up. When I was finished and re-installed the rear deck, I ran the hydraulic steering line on the wrong side of a brace and then for good measure, ran one of the decking screws right through it. At least twice that day I had the boat take a full-lock turn at nearly full speed because there was no pressure on one side of the pump/ram. Nobody got hurt, but it's probably the most potentially dangerous thing that's ever happened to me in a boat.
The least pleasurable day in the boat was probably memorial day weekend in either '04 or '05, it snowed in Devils Lake and we fished anyway. It was cold, windy, miserable, and we didn't catch any fish but I didn't ever feel like we were in any danger.
The strangest, and also possibly dangerous day was in March of 2012. Put in @ Hazelton and ran south until we hit a fog bank. Shut down, used the trolling motor to keep us in the depth I wanted. However, the fog was so thick that neither GPS would acquire a signal, and eventually we were in the fog long enough that nobody could tell which way we were drifting, nor which direction shore was. Came out of the fog just above the Ft. Rice ramp. Very lucky that nobody decided to be a knot-head and rocket through the fog. But again, didn't ever really feel like we were in any real danger, it was just strange.
