Grilled Cheese and Ketchup

While sifting through the Sandwich Blog mail pile the other day I stumbled across a pressing question from a tipster: Is a grilled cheese dipped in ketchup right? Or horribly, horribly wrong? The tipster included this photo evidence:


I don't know, guys. My gut instinct is that this is a disgusting affront to sandwichery in general and grilled cheeses in particular, but I also know deep down that this stance is rooted in personal biases, tradition, and a reluctance to stray from societal norms. I know I'm being closed minded. I mean, I don't care what you do with your sandwiches in the privacy of your own home, I just hate having to see it, you know?

(This is a grilled cheese on challah from B&H Dairy.)
