Now I've seen everything.  A Cheeseburger.  In a can.  Simply boil it in the can, then eat it.  Reviewers tend to agree it tastes somewhat less in quality than a McD's Cheeseburger... but, I guess it's useful if you are going somewhere with no refrigeration or ability to get fresh beef.

That's just gross.  I can't imagine sinking my teeth into it.

Oh come on Hawkeye.. you were in Scouts, so you HAD to eat something worse than canned hamburger meat... what about a peanutbutter and crap-hand sandwich?

Never ate that... left it for Weppy.

Heh heh heh, I know, I remember.. just laughing about it is all
