This is entirely a Leo Smith creation. I was a fortunate bystander in the whole thing, really.
Sometimes, there are two games on that you want to watch. And they're on at the same time, but on different channels. So how do you deal with that kind of connundrum?
Record one while watching the other, and watch the recording later? Sure...that's an option in many homes nowadays.
Go to a bar that has more than one game on at a time? I suppose. But you can't wear your jammies to a bar without opening up the possibility of people pointing and laughing/scaring people.
How about you get a cable splitter, get a TV from a room that no one is in very often, and hook it up right next to your other TV that you usually watch things on?
DING DING DING!!!
