Yes Goodness!
Have you ever held a laugh in so long that tears came out your eyes and you started shaking? 
Oh yeah. Funny story:
We were at a funeral, and the dude who was preaching kept saying the word 'typoon', instead of typhoon. He was loud wit it too, like he just knew what he was talking about. If he would've said it one more time, church would've been out.
My entire choir was holding back laughter. One of my choir memebers acted like she was crying, when she was really laughing. Another choir member had to leave completely cuz tears was rolling down her face.
