A guy at school needed the toilet. He wasn't allowed to go (none of us were in lessons). So he BEGGED the teacher, she said no again until he was bursting. He finally got to go and was holding his pants.
He got to the door, but our old school doors were those with the knob and latch separated so you had to open both at the same time to get out

so.....he had to let go of his pants (and that river flowed....

) There was urine everywhere, and the door was wet too so his hands were slipping all over whilst trying to open the door
EVERYONE was screaming with laughter, even the teacher (who tried to get us all to stop). Then he got out but he'd finished

and then left a trail down to the toilets lmfao

The head of security/discipline came and yelled at us all....it was soooo funny.
2nd story:
our Biology teacher was behind her classroom door and she was 7 months pregnant. My best friend rammed me into the door after Computer class as a joke. OH MY GOD. She was half an inch from being hit by the metal handle. I could've KILLED her child

I never forgave myself. She was furious.
