Ed Goldstraw has sent another joke:
The Thames river police stop two Pakistanis' in a row boat, rowing towards central London. "The captain gets on the loudhailer and shouts "Ahoy, small craft, where are you heading?"
One of the Pakistani gentlemen stands up and shouts, "We are invading the United Kingdom."
The crew of the Police launch all start laughing and when the captain finally stops laughing, he gets back on the loudhailer and says, "Just the two of you? I think you'll need more than that."
The Pakistani gentleman stands up again and shouts, "We're just the last two. The rest are already here!"
