Paddy's Aptitude Test

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!
