Irish Accountant

Paddy wanted to be an accountant, so he went for an aptitude test.

Tester: If I give you two rabbits, & two rabbits & another two rabbits, how many rabbits do you have?

Paddy: SEVEN.

Tester: No, listen carefully again. If I give you two rabbits & two rabbits & 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 & 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!
