Sit down in front of the TV, and flick through the channels in the hope of finding something interesting. Spot Master and Commander: The Far Side of the World, and start watching it. Get up during a commercial break to take supper out of the oven, and realise that you a) own the DVD, b) the DVD will be better quality, and most importantly c) the DVD doesn't have commercials. Put the DVD on at where the broadcast left off, and then 2 hours later wonder where the time went.
