You probably know some real dummies. We certainly do. Just the other day we heard a guy saying that people 'misunderestimated' him. Sadly it was the President of the United States. Still, at least ol' Dubya can console himself with the fact that language mangling is not a measure of intelligence.

To truly gauge a person's brain power (or lack of) you need to test their cognitive abilities. And there's no better way to do so than with the brilliant Pocket IQ Test.

This handy little pocket-sized kit will give an accurate rating of your IQ in under 45 minutes. Simply answer all 60 of the multiple-choice questions printed on its laminated fold-out cards, add up your score and your IQ will be revealed. Scary, eh? Why not give it a try with these sample questions:

The questions vary in style, from odd-one-out and next in the sequence, to word puzzles, spatial reasoning and those infuriating 'Mary had five cookies, ate one, halved two...' style riddles that will have smoke coming out of your ears from concentration. If you don't know the answer to any of the questions you can guess, and this is taken into account when scoring.

The Pocket IQ Test is an absolutely brilliant take-anywhere party/bar game as it invariably brings know-it-alls down a peg or ten. And you can't argue with the result. Well okay, you can, because although IQ tests were once the standard measure of human mental capacity, some experts now reckon they're unfair. But hey, that's life. Besides, this makes it all the more amusing/controversial when someone gets a subpar brain rating. Or a high one for that matter!

Whether it's out of vanity or simple curiosity, this is one test people simply can't resist taking. But the hardest question of all is this: have you got the guts to take the Pocket IQ Test? Well have ya, dunce? (No, we're not revealing our score).
