Rabbits
Paddy wanted to be an accountant, so he went for an aptitude test.
Tester: If I give you two rabbits, two rabbits, and another two rabbits,
how many rabbits have you got?
Paddy: Seven!
Tester: No, listen carefully again. If I give you two rabbits, two
rabbits, and another two rabbits, how many rabbits have you got?
Paddy: Seven!
Tester: Let's try this another way. If I give you two bottles of beer,
two bottles of beer, and another two bottles of beer, how many bottles of
beer have you got?
Paddy: Six.
Tester: Good! Now, if I give you two rabbits, two rabbits, and another
two rabbits, how many rabbits have you got?
Paddy: Seven!
Tester: How on earth do you work out that three lots of two rabbits are
seven?
Paddy: I've already got one rabbit at home!
