There are some things that you just can't plan for - like falling into a river in such a comically slapstick way that it looks 100% staged.

However, this wasn't the case with Twitter user James Moss, who in fairness was able to laugh about the whole thing afterwards.

Moss was on a team-building day out with his colleagues in London the other day when he and a friend took part in what was supposed to be a funny video filmed by their boss of them walking down the steps to the river Thames, pretending to take their t-shirts off to go in for a dip.

Unfortunately for him (but fortunately for us), he barely made it halfway down before he slipped on the mossy steps and tumbled down one (comically slow) step at a time until he fell in.

To be honest, seeing his mate doubled over in hilarity and the reaction of the man filming is almost as funny. We must have watched it twenty times already.
