I saw a couple of guys watching water skiers taking off from a beach by taking off from dry sand. The boat pulls the line tight then guns the engine pulling the skier smoothly onto the water.
They tried to do it themselves. The guy threw a big coil of rope on the sand in front of him and told the boat driver to "Hit It!". By the time the loose rope ran out the boat was going full bore and snapped the skier a good 15' from shore.
Perhaps I shouldn't be laughing as it dislocated both of his arms. But others tried to tell him what he was doing wrong and he wasn't about to listen.
I saw this from a bluff overlooking the lake. From my vantage point it was pretty funny.
