Lmao! Yes happened to me in Aldi. Bent over to pick up a pallet and my trousers just like yours split round from the crack to the zip at the front. And I still had 11 hours and 45 minutes to go…
this is why i only wear Wrangler jean, (other brands are available), LOL
when i was working at arcese we used to deliver real heavy gkn blue boxes to the meritor plant at cwmbran[1650kgs].My friend and colleague tony s***t lept into the trailer saying “give me a pump truck and well tip thru the back doors,save undoing the curtains”.they duly obliged and he keenly set to work skillfully lining up his first lift pumping with great vigour he then heaved and heaved then proceeded to fill his underpants dropping the whole sailor in the hamock.then gingerly made his way to the back door asking the forklift driver for directions to the lavvy.Bit of a ■■■ in my book
I’ve done that so many times doing pallet network type work. Lean over to shift something, put a bit of force behind it and then tear your trousers right open.
I never learn.
Just a note… it isn’t exclusive to being a fat blob. I’m 11 stone.
It’s to do with your trousers sitting too low, just like people in expensive suits pulls the knees up before they sit down. Same principle. Easy to forget when you are in a hurry though.
While we are on the subject of stupidity. I was once trying to push an extremely heavy bale of hay off the side of a wet wooden boarded flatbed. I slipped, went undercarriage over fuselage and was about to take a tumble off the side of the lorry very much head first, when I just managed to squeak to my mate “Grab me”. He took a dive and caught a handful of my trouser leg just by the cuff as I was in mid roll. Then the whole world paused (he was a big lad), and disaster was suddenly avoided. 
Bought him a few pints that week.
I thought you had stopped getting your helmet out in public.
