A few years ago, I needed to pick up a heavy package (an APC SmartUPS) at work - as I was bending over to get into the correct position for a heavy lift, I heard a rip, and supposed that I had split my trousers.
When I inspected the damage, I found that I had indeed split the seam - I was basically left with two trouser legs hanging from the belt loop.
One of my colleagues witnessed this - and told everyone - I got so many texts of congratulation it overflowed the inbox on my phone.
