Are you sure? 
If a plane carrying 50 Americans and 50 Canadians crashes right on the border between the U.S. and Canada, where do they bury the survivors?
WOW, is that an old one.
You don’t bury survivors, duh. :-p
Not if you want to collect the insurance.

no message. I just thought that the smilies in the spoiler boxes looked cool.
Dude, if you’re allowed to take the cans out, then you can visually determine which cans are larger. No need for a scale.
'Course, we could hypothesize that these are all 12 oz cans (or so), giving them a uniform size. Of course, they’d all be partially full. Even then though, you can pretty much tell which cans contain the extra ounce just by hefting them in your hand.
Now, we could postulate that the cans are so heavy that no human being would be able to tell the difference by hand, but that strikes me as a needlessly elaborate restriction to add.
Car Talk had a puzzler recently that was similar to the cans puzzle, only more elegant and harder, IMO.
Basically, you got seven piles, a hundred coins in each pile. Each pile is composed entirely of either real coins (which weigh 10 grams) or counterfeit coins (which weigh 11 grams). You’ve got a very accurate digital scale, and need to figure out which piles of coins are real and which piles are counterfeit. What’s the fewest number of weighings you need in order to accomplish this task?
Car Talk gave a hint, which flabbergasted me:
you only need one weighing
and so I spent the next half-hour of my drive trying to figure out the answer. I got the basic principle fairly quickly, but it took me awhile to figure out exactly how to accomplish the trick, until I remembered the following, which is a much bigger hint than what Car Talk gave:
binary code
That was actually a pretty good puzzle. Some of those lateral thinking puzzles suhuck: the answers they provide are nowhere near as elegant as some possible answers would be.

Gotverdomme! I forgot how to spell! :smack: (I won my school spelling bee in the fourth grade. My teacher would be embarrased, to say the least.)
I just love “gotverdomme”. When pronounced correctly it sounds much better than “Goddamn”. Not only does it mean the same thing, but it actually sounds like you’re spitting up a hairball at the same time you’re cursing! 
The correct spelling is of course: “weigh”
If you liked Mindtrap, you’ll like Crack the Case. Each card is a murder mystery, and you give the scenario and answer yes or no questions until they solve the puzzle.
I love these games. It helps you expand your mind. But it was funny playing the game because as you went through the cards the murders got more and more convuluted, so we’d start by shouting out, “Did she die by electrocution with a VCR and a hot tub?” “Did he die because a bird pecked him to death?” “Did she die by eating poisoned ice cream?” because those were solutions to previous mysteries.

Review of Crack the Case.
Yeah, not to mention that the agent’s name must be Raymond Babbitt, if he instantly recognizes the name(s) and connects them with the two-tickets-buying guy. :rolleyes:
