It might seem impossible to say anything coherent about such an eclectic mix of places.

要讨论这种风牛不相及组合的相关性似乎是不可能的。

And I would say, it's a bit of apples and oranges.

，这简直风牛不相及。

They originally had nothing to do with each other.

它们原本是风牛不相及的。

It's, it's, it's, uh, a totally different situation! It's, it's apples and oranges, it's, it's orthodontists and lesbian- I gotta go.

这是，这是，这完全是两回事，这是风牛不相及的事，这是牙医和女同志的，走了。

And if you are compare apples and oranges you are comparing two things that are so different that any comparison is really not productive.

如果compare apples and oranges-把苹果和橘子一起比较，就是把风牛不相及的事物一起比较。
