Just witnessed whilst walking the dogs: a cyclist riding past a group of folks just hanging out and then throwing an egg at them.
The cyclist missed, but the group didn't.
Top-tip: when doing such a "prank" make sure you can out-pedal the fastest sprinter in the group, or things will end badly for you.
