Remember this video showing some stupid tourists getting in the way of the Queen's Guard? Turns out they weren't the only tourists to fall foul of them.
Check out this video of one tourist who thought it would be a good idea to hassle one guard who was just doing his job... We think he probably won't do it again.
We think the lesson here is probably "don't touch a highly trained soldier who is carrying a massive gun".
The video appears to have been shot at the Tower of London - let us know if you know any better in the comments.
