Just blag it. My father says he has a degree from the London School of Economics. I guess if you are going to blag, you might as well blag big.

My father in law says he has a degree in engineering (in reality started but never finished).

Neither one of them has ever been busted for it to the best of my knowledge. On the other hand I have a real degree from a real university. To think that I could have instead just spent those four years drinking beer, smoking pot and chasing girls. Oh, wait...
