Worlds safest excuse.

Last night I broke into the local bank, blew open the door into the strongroom and spent four hours with a blowtorch cutting my way into the safe. Filling several bags with used notes I was making my getaway when all the alarms went off and I was surrounded by the law.

"Good grief!" said plod "How on earth did you get so far without the alarm getting tripped?"

They had to let me go when I quite rightly pointed out that I am an MP and that it wasn't me but the system that was at fault.
