Oh yes, I hate burgers, never want one, and yet, even they filling up a screen can make me want one.
I subscribe to Bon Appetit, love reading and drooling, and sometimes cook from it. A recent issue had an ad for Lindt Chocolate Excellence bars. I ended up buying one just based on the ad generated craving (well, at least it wasn't a car I impulse bought based on an ad!) - I've been able to eat a small amount a day, but really, I know better!
