Naw we were always playing practical jokes on each other.
We had to crap in the marsh as there was no cover, normally we buried it but one guy said he was so proud of it he wanted the world see how large his !!!! was. We stole his 8mm Camera found it and filmed it for him, when he got home his mother had the shock of her life when he played the film to the family on a projector screen.
Probably the best one though was one of the girls who wanted to go stargazing as it was so dark, she went away from the camp site and lay in the open looking up at the sky. About 3 hours later the police arrived saying they had had a report of a dead body from a passing motorist. The cops had driven 30 miles, they were not happy bunnies.
