Watching Food Network Makes Me Hungry. Duh?

O.K. I know it's pretty obvious but watching the Food Network makes me hungry.  Its the same when I walk down the ales of HEB.  You see food, you get hungry.  I always thought the Food Network was a cable channel of people cooking food; and for the most part it is. But THEY SHOW ALOT OF CLOSE UPS OF FOOD on that network. That's how I stumbled on to this channel. There I was switching from ESPN to probably HBO, when I see a close up of what the guy on tv was calling Chahos; thats like Nachos but made with Potato Chips. So, I left it on the channel for a bit...then a bit more...then a bit more. I was scopin this channel out like I scope out the fridge when I open the door and go through the possibilities of snacks I can eat.
