...... once you've gone black you'll never go back.
Which reminds me of a line in a recent episode of
Two and a Half Men I watched on the Air New Zealand flight back from NZ.
This was when Alan's (lesbian) neice takes a break from 'entertaining' a girlfriend in the bedroom to take an appliance out of a kitchen drawer. The appliance was a large electrical item with egg beaters / mixers attached. Walden comments (something along the lines off), "Once you've gone
Black & Decker, you never go back."

Well I thought it was funny ................

My experience with
Black & Decker is that once you've brought
Black & Decker, you'd never buy
Black & Decker again.
