I saw some daytime TV programme once in which the premise was that people's home security was tested by a reformed burglar, who'd try and break into their houses while they watched on CCTV from afar.
One particular family, aside from being happy their house was like Fort Knox (wrong), were content in the belief that, should the "burglar" manage to infiltrate their security system (he did with ease), their pet dog would savage any intruders, or at least bark loudly and alert neighbours.
It was priceless seeing the look on their faces when this complete stranger broke into their house, and not only did the dog fail to savage him, he didn't even bark. Instead he sat on the sofa, tongue hanging out, while the burglar bagged up their possessions.
The best bit was at the end, when the burglar calmly attached a lead to the willing mutt's collar, and led him out of the house, all the while the dog wagging his tail happily at the unexpected walkies.
