i had a similar incedent years ago at work we were on a tower scaffold working on the main canopy of hilton park lane as it happens
i was bending over to pick my tools up and the guy i was working with had a dril with a 1/2" hss bit in it. He made a gesture as if he was going to shove it up my bum to the blokes on the ground below
At that exact same moment i moved backwards and the drill caught my jeans. Un beknown to me the struggle he was having to stop it actually ending up, up my bum until i turned my head to find out wtf was going on and saw the fear in his face the drill in his hand and my jeans dissapearing around the drill bit. More importantley quickly realising the direction it was heading
a joint effort ensued to ensure we did not loose our only 1/2" drill bit. Thankfully with the ripping of denim the drill was free with the arse of my jeans wrapped round the drill bit and chuck
the blokes on the ground were pissing themselves we on the other hand had to 1) prise my hand off the tight grip it had on the scaffold and 2) prise the drill from my very white work mate before we could laugh about things
RIP Fred sadly no longer with us
