I've been thinking about this since Thanksgiving (there's almost always a platter of cheese, crackers, and summer sausage).
Of all the cheese I can think of, there's only one that I don't really like. Swiss.
Swiss is tolerable maybe even ok on sandwiches or burgers, but alone, or just by itself on a cracker – BLECH!.
Luckily the darn stuff has holes in it, sparing a random section of my tongue from the swissness with each bite.
