Ok, here's the answers:
1. True - not my proudest moment, but it happen on a soccer field in a national tournament. I can't say it was entirely an accident, but I did feel bad later (we lost the game too)
2. True - my son was playing on a dock in a man made pond and fell in. He was about two and a half. I jumped in fully clothed and didn't have to go as far a mouth to mouth, but he had swallowed a lot of water by the time I brought him up. Ruined a perfectly good pocket watch too, which I tease him about to this day ;-)
3. True - and a lot easier than you might think
4. Which makes this the lie - Never cheated - thought about it from time to time, especially for Thermodynamics,but never did.
