I've seen a lot of funny things, a lot of dangerous things, and definitely a lot of stupid things.
One of my favorite stupid/dangerous things was with a student in an AOW class a couple of years ago. It was December, and I took a class of 4 students to do their "Deep" and "Wreck" dives on the recently sunken HMS Yukon in San Diego's Wreck Alley (should be called "artificial reef alley").
Anyway, the Yukon is on her port side in 99-102 fsw. I took the students to 99 fsw and had them work a "narcosis" puzzle. This took 10 mins. I then took them up to 70 ft for a short look around before beginning a slow ascent. Student "John" indicated he was at 1/2 tank, so we headed up the ascent line as planned. We stopped at 15 ft for a 3 minute safety stop. All four students hovered nicely, fingers lightly cupped around the mooring line (not gripping), as instructed. As I scanned around watching the students, a pair of fins disappeared above me just out of reach kicking frantically. We were perhaps 20 seconds into our stop. I had to let the student diver go since it would have served no purpose to chase him, and take a chance on causing the other students to panic and follow me to the surface in the 10 ft visibility, risking injuring to them.
Upon reaching the suface, exiting and finding "John" to be okay on board the diveboat. I asked him what happened. He said he was down to 500 PSI and he had been told to always surface with at least 500 PSI. I was speechless for a moment, then told him to be sure and just stop his car on the freeway and get out if his fuel ever gets down to an eight of a tank.
