Two men try to get into a restaurant but both have their dogs with them – a Labrador and a Chihuahua – and are refused entry by the doorman. The two men put on dark glasses and try again. ‘Can you let me have a table?’ asks the man with the Labrador. ‘I know I have a dog, but I’m blind and this is my guide dog.’ The man is let in, and the second man tries his luck. ‘Can you let me have a table for me and my guide dog?’ he asks. ‘That’s not a guide dog,’ says the doorman. ‘That’s a Chihuahua.’ ‘A Chihuahua!?’ shouts the man. ‘Those bastards gave me a Chihuahua?!’
