It's one of those freak things that happens.

I could get new pants if I weren't such a hippie freak.

There are certain authors that do not turn students on; it is the truth. Homer happens to be one of them.

He's not a fumbler. I suspect we won't see that again. I think one was a freak thing, and the other he got careless driving for more yards.

We had one burp there. That just happens.

There's more than one individual, so they can refute the hypothesis that this is just some kind of freak. Also, the data suggest that [the remains are from] a fairly long time span, so that makes it tough to say that this is [due to some sort of disease].
