The vast majority of these puzzles seem to be trick question involving words. That is, their intention is to deceive the inattentive listener with an unexpected or unnoticeable wording. They are not so much puzzles of logic or even "thinking outside the box", as they are tests to see if you can catch which word is the unexpected one.

Is that really what "lateral thinking puzzle" is? Wordplay? I would have thought of it as being something smarter. Something that makes you go "ah, clever, I didn't think of it like that" rather than "that's dumb, you just tricked me with unclear wording."

Which of these two weighs more? A pound of gold or a pound of feathers?

• Actually, the answer "they both weigh the same" is wrong. Precious metals are weighed in the troy system (troy ounce=31.1 g, troy pound=12 troy ounce=373 g), just about everything else in the avoirdupois system (avoirdupois ounce=28.4 g, avoirdupois pound=16 avoirdupois ounce=454 g). So an ounce of gold weighs more than an ounce feathers, but a pound of gold weighs less than a pound of feathers.

[Okay, it's already mentioned in the page.]
