little johnny wanted to be an accountant, so he went for an aptitude test:
tester: if i give you two rabbits, and two rabbits, and another two rabbits, how many rabbits have you got?
little johnny : seven!
tester : no, listen carefully again. if i give you two rabbits, and two rabbits, and another two rabbits, how many rabbits have you got?
little johnny : seven!
tester : let's try this another way. if igive you two bottles of beer, and twobottles of beer, and another two bottles of beer, how many bottles of beer have you got?
little johnny : six.
tester : good! now, if i give you two rabbits, and two rabbits, and another two rabbits, how many rabbits have you got?
little johnny : seven!
tester : how on earth do you work out that three lots of two rabbits is seven?
little johnny: i've already got one rabbit at home!
