Silly Pranks
The prevalence of downright evil in the name of ‘pranks’. The worst I have seen were some guys that threw a Baby doll face down from a bridge in a river. Then they started screaming that a baby was drowning.
A shocked man was about to jump in the water to save the kid when they burst into laughter. At the last second, they informed him that it was a prank. Guaranteed that this brave man will think trice before he will ever show such civil courage again.
