I studied abroad in Ireland for a semester, and that included doing my own shopping. I was at the grocery store with one of my Irish roommates, who was living on his own for the first time.
We were in the freezer aisle, trying to stretch our money as far as possible, when we saw "30 hamburger patties" for the equivalent of about $4.
We thought we scored, until we got home. The "hamburger" was white and looked chalky, and didn't look like any beef we'd ever eaten. At that point, I read the box, and there was a small box on there that said something along the lines of "Does not contain more than 40% sawdust". Seriously. Sawdust.
Undaunted, we both decided to be adventurous, assuming that they weren't *that* bad. They were. We couldn't eat those things even when completely blitzed. We tried pawning them off on other roommates, friends, etc., but nobody could get one down.
It's definitely not as cool a story as some of here, but it still cracks me up.
