I have never actually had Spam - what does it taste like?
The two grossest things I ever felt obligated to eat were a tuna fish sandwich made with Miracle Whip, and a grilled cheese sandwich made with WAY WAY too much Velveeta (think "globs"). Both of these unfortunate items were served to me when I was a guest. Usually I'll try to choke down anything I'm served out of politeness, you know? Those are the only two things I can ever remember just not being able to eat, even to be polite.
What was the worst thing you ever felt obligated to eat?
