That new satellite dish of yours is picking up all kinds of strange and interesting channels. Great Gatsby! You've zoned in on Googol Television, better known to tube-zombies as GTV.

Sitting around all day watching this stuff can be a really bad habit. If getting off the couch isn't an option, the least you can do is exercise your mind.

Begin your mental workout by changing the channel, again and again. Check out what else is on. Click your way up and down the TV-dial until you've witnessed each and every one of GTV's action-packed 30-channel menu.

And while you're at it, try to remember what you've seen ... because we're going to start asking you questions about what's on.

If your memory is really sharp, try answering questions with the set turned off.

When your brain starts hurting, don't panic (that's a normal side effect of educational television).
