Mass brawls where all the players are involved and you know that there'll be at least two red cards.
A winger (Kebe/Gilkes) simply knocking it past the full back and out-sprinting them.
Players celebrating a goal by jumping in with the fans.
Walking to an evening game as kid with the floodlights coming into view.
A shot hitting one post, then rolling across the line, before hitting the other post and bouncing harmlessly away.
The fact when walking through a crowded street, I pretend I've got a ball and am actually dribbling past people.

The simplicity of the game. "Right lads, here's a ball. Go and play with it. Just don't use your hands."
