Well, here are some of the reactions I found to the Cheeseburger in a Can at http://www.avclub.com/articles/taste-te ... -can,2183/, where you'll also find video, stills and blow-by-blow commentary:
• "It tastes like the hamburgers that you get in elementary school."
• "Oh, auuugh. It's awful. Have these people ever had hamburger before?"
• "Boy, that taste really stays in your mouth, doesn't it?"
• "That was so bad."
• "I think it's more the soggy bun than the meat."
• "No, it really is the meat that's the problem. Oh God."
• "It's like the Salisbury steak in a cheap TV dinner."
• "It's like Upton Sinclair nightmare bratwurst."
• "It tastes like Spam. Spam, but chewy. The texture's about the same."
• "It is a little smushy. It's spongy. I don't hate it. I think I could eat it if it was hotter, and I could dip it in Ranch dressing."
• "I cannot swallow this. It will not go down."
• "It's not quite meat, is it? It looks like freaky airline food."
• "It tastes like beef-flavored something. Beef-flavored matter."
• "It's a really dense meat-like puck."
• "When I first tasted it, it didn't bother me, but it festered." "Really? I gagged the second it hit my tongue."
• "It was still way better than I thought it was going to be. It wasn't nearly as slimy." "Yeah? It was exactly as bad as I thought it was going to be."
• "It's pretty much like a dog-food patty."
• "It tastes like something that was dropped on the floor. It tastes like a 7-Eleven hamburger that's been sitting around in the store for a couple weeks."
• "It's like this chicken-fried steak that I got once at a disreputable diner, then left in the fridge for three days, then ate in a drunken stupor. No, it's a little worse than that."
