Don't you get them sold in different bottles though, as if they're two different things, or is Ketchup just sometimes called Catsup by companies run by loons?
I honestly don't remember seeing one that actually says Catsup, but I guess I have never paid much attention, I don't really like it so I don't buy it But now curiosity will get the best of me and I will have to look
Did you never see that episode of the Simpsons, where Burns was broke, and he was staring at a bottle of Ketchup and Catsup in a supermarket and looked confused .
