I believe that's the point in B1S2's journal we stop the madness. Sexual stuff, even jokingly, that gets to that level, is where he draws the line. If we want to continue the spat, it has to be in PMs. Lord knows, in my own journal, this would have been quashed long ago.
It depends on the sandwich it is being put upon. If it is a burger, it is yellow American, preferably Kraft. If it is on roast beef, it is preferably a double gloucester. If it is a grilled cheese? Kraft sharp cheddar. Why do you ask this?
You can tell a lot about a person's character by their cheese preferences. You pass the test. For me it's a toss up between smoked gouda and smoked blue cheese.
Good lord, you really are not right in the head. Smoked cheese belongs nowhere near a sandwich, That's on the side or something. I bet you put ketchup on hot dogs, also. I grew up in New York. Mustard on hot dogs, ketchup on burgers. No fuss, no muss. And in NY, a "regular" coffee has cream and sugar, damnit!
