Why on earth did he have to do such a bizarre combination of things?

He knows that perfect combination of things to talk about.

It was not a combination of things, but one thing.

"I'm sure it's a combination of things, but you have to learn how to win on the road."

It was a combination of things, I guess, and no one special reason.

Every terrible thing in the world was caused by a whole combination of things.

"It's going to take a combination of things to happen."

"I don't even know exactly what combination of things he's taking," she said.

The crowd gave him a hard time because he was so good and probably a combination of other things.

But it may be a combination of things as well.
