We British love a bit of dark humour, but there are no hard and fast rules to help us draw the line between sharpish fun and plain cruelty. We found it interesting to contrast these two ads. The first is from WKD alco-pops and is about playing practical jokes on your mates. The second is from Burger King and tries to make a connection between the darkness of the Dark Knight (Batman) and people’s ill intentions.
