What decade were you born?

I think you need a biology lesson. LOL! If he were born in the first few months of 1980, he would have had to have been conceived in the 1970s.

Yes...that's why I said "You are either born in 1980 or an elephant". I saw two possible cases consistent with what he said:

1) He is a human being, conceived in 1979, born in 1980.
2) He is an elephant, conceived in 1979, born in 1981.

Although there are two other possible explanations, now that I think of it:

3) He is an elephant, conceived in 1978, born in 1980.
4) He is an elephant, conceived in 1979, born in 1980.

EDIT: Although I do admit I need a biology lesson. My wife keeps telling me this. I once asked her the question, in all seriousness, whether pregnancy tests give valid results while a woman has her period.

Born in July, conceived in November.
