I'd been riding clipless for about 5 years with no incident (though yes, I had the same first-time slow-mo "ohhhnoooooooo" moment my first time out) when I went on a century plus ride with a friend. Mile 80 or so we stop at a convenience store for some stomach fuel. I pull up beside him and slow-mo repeats itself. I put my hand right through his rear wheel and spent the entire rest break re-truing if for him and apologizing profusely. He just laughed. Whoops!
