this Russian joke illustrates how context and culture affect the tenor of humour. Think back to the late 80's.

a man joins a queue at his local supermarket. Hours later he has not moved. Next day he is getting nowhere and restless. A week passes, then after a month's queuing he declares to the line of waiting shoppers he is so fed up he is going off to shoot Gorbechev amid shouts of encouragement.
An hour later he returns. The people are abuzz asking how it went, did Gorbechev get just desserts? Nyet - the queue to shoot Gorbechev is longer than here!
