According to many theorists of humour, a funny event must contain one of three elements to be truly comedic.

The first is incongruity. So let’s imagine a man sitting on the toilet reading a newspaper: not funny. Not until you zoom out and see that the toilet the man is sitting on is actually at the centre of an installation in a modern art gallery, surrounded by bemused members of the public. The man gets up and flushes the toilet, and instantly the entire gallery and everyone in it disappears. For the second element of comedy is surprise.

The third element is recognition, which is why the fact that Arsenal have been drawn with Bayern Munich for the fourth season out of five may not be incongruous or surprising, but is still pretty funny. The memes were pinging around the internet within miliseconds of the draw being made - almost as if they had been prepared in advance. “Hello again!” tweeted the official Bayern account at the official Arsenal account, accompanied by a meme from Groundhog Day. Truly, we are living in a post-banter world.
