split one's sides

God looked at it and began to split his sides with laughter.

He lifted the shoulders of a poor fellow covered with mud and blood, who was laughing to split his sides.

I split my sides laughing, escorted him off the premises, and sent that first letter to you.

When he got home he would split his sides with laughing.

"Even his own guards were trying not to split their sides laughing."

It would have made you split your sides with laughing.

The grown-ups split their sides laughing, and we enjoyed ourselves every bit as much.

We split our sides laughing, as if she'd told us a good joke.

Not in a way that you'd split your sides over.

With that he laughed fit to split his sides.
