Or the illegal aliens? (I'm allowed - I was in a relationship for 5 years with a Honduran woman)

Many years ago, one of my co-workers locked himself inside an armoured truck, at end-of-day on a Friday. The lock was broken (one of the things we were working on. All the glass was bullet (and sound) proof.
It was just he and I locking up and I was closing the garage door. I looked for him to say good bye, figured he had left. I turned the light out and was just about to leave, when I see movement in the truck. I do a double take and almost fall on the ground in laughter. My poor buddy was panicked, screaming and banging on the bulletproof glass from the driver's seat, but there was no noise at all.
I got him out, but it could have been a terrible predicament.
Still makes me laugh.
