Admittedly not on the water and no gear was harmed (except for my noggin) I was wondering if the following qualifies as an Elmo?
After getting pressured into putting up our Xmas light street display I thought I would clean up the lawns, edges etc in the process. I had pretty much filled up one giant wheelie bin with clippings, palm fronds etc.
I was wheeling it down a path outside my place with the lid open and hanging down. As I went over a step the bin dropped and I struggled to hold it.
I then proceeded to tread on the big lid, tripped and ended up kneeling down on the lid going downhill and accelerating.

The bin then impacted with the side of our house, I threw out my arms to minimise impact, miised and my hands and arms ended going into the grass clippings inside the bin which let the top of my melon impact with the sharp bin edge.

I sat there stunned a bit, then looked around to see if any of my neighbours saw my stupidity. Nothing.
I then gingerly felt my head which was now bleeding profusely. After some colourful language my wife and daughter came out to see what the fuss was about.
Can you beleive it?, the buggers laughed.

Here endeth my story.
