Anyone ever have an Uncontrollable Laughing Fit ?

I mean like when you're trying to tell a funny story (that may not even be 'that' funny), but all of a sudden, you can't finish the story because your laughing so hard you can't get the words out?
And when you can get something out, it comes out in little girlish sounding squeaks n squeals, until you finally give up?

And everyone in the office is staring at you like your cheese has completely slid off you cracker....?

Yeah, that just happened to me....
