I was running along a street in a built up area, lots of traffic not many predestrains, I had my earphones in but I had Laura turned down a bit - so I don't get run over while trying to improve my health (!)- I heard someone shouting in the distance, bit odd, the shouting got louder and closer and I heard "Bet you wish you hadn't ate all that pudding, get your knees up"- thought cheeky sod turned round to give an earful, behind me was a running club/squad, and the cheeky sod was the "leader" running on the opposite side of the road, shouting and roaring at them.
It did make me laugh, but they are paying for it so I guess they must be enjoying it!
