Ketchup Grilled Cheese - cooking recipe

Ingredients

2 slices bread, your favorite kind
2 slices processed American cheese (Kraft, Velveeta, etc)
2 -3 tablespoons ketchup (I eyeball it, but I'm liberal about it)
butter or margarine

Preparation

Heat skillet/frying pan over low-medium heat.
Spread butter on one side of each slice of bread. Place cheese between unbuttered sides of the bread.
Grill sandwich on each side, flipping when the butter on the edges of the top slice begins to melt. Make sure cheese is nice and melty.
As soon as the grilled cheese is done, move to a plate and partially lift up the top slice of bread (keep the corner of the sandwich \"attached\"). Cheese should be very very melted and almost runny still.
Very quickly (before cheese hardens) squirt ketchup in between the two slices of bread, as evenly as possible.
Replace top slice of bread. Enjoy over a plate, as ketchup will probably seep out :).
