I was playing at my local par 3 last year in March. Being England it was very wet and there is a lake on the last hole, the 9th with a very steep bank.

I hit my sandwedge shot then walked to the green. The ground gave way and i slid down the bank into the lake, with my sandwedge still in hand, and swam about for a bit before getting out. I dropped my sandwedge in an attempt to get out and its still in that bloody lake! lol
