A bloke walks into a pub, buys himself a drink, leans over to the bloke sitting next to him, and says “Want to hear a joke about a London office agent?

The bloke next to him replies, ” Well before you tell that joke, I think you should know that I’m 6 ft tall, 18 stone, and I’m a London office agent. My friend and colleague sitting here next to me is 6 ft 2, 19 stone, and has something of an anger-management problem – he’s also a London office agent. Now, do you still want to tell that joke?”

The first bloke says, “No thanks. I don’t want to have to explain it twice!”
