Classic AL, the centre spot on the back window
Sorry to say I am still laughing at my beer glass one.....
Oooh, here's another one:
* When friends ask to see photos of your loved ones, you flip out your wallet and pics of Jupiter, Omega Centauri and M104 fall to the ground....
* The spy eye in your front door has a cheshire cross hair in it.
* Your shaving mirror is BK7 with better than 1/12 wave dispersion.
