Just can't help but laugh...

I was sitting in the doctor's office today with my grandmama. The guy sitting relatively near us had his cellphone, but obviously forgot to silence it. While the room was dead silent, it goes off and I hear this: "You have another f*cking email." He heard it start to talk and out of the corner of my eye I saw him frantically try to silence it, to no avail. I just could not help but laugh. Grandmama asked me what I was laughing about (because of course she didn't hear it...) and I'm not sure I could have used the F-bomb in my Grandmama's presence...so I just said I read a funny joke on the internet. That satisfied her.
