I couldn't stop laughing as we started to move on green.

I can't stop laughing all the way up the street.

And all the way back he just couldn't stop laughing!

He put a hand over his mouth and tried to stop laughing.

I pretty much did not stop laughing for three days, that time.

It took a long time for them to stop laughing.

All the same, he found it difficult to stop laughing.

Very good they are too: it's taken me a whole month to stop laughing!

Then you stop laughing and wonder what the point is.

I had most of it worked out by the time I'd stopped laughing.
