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 is seven? Paddy : I've already got one rabbit at home!
