One Time I Laughed Really, Really Hard

One time my mom, sister and brother in law and I were going christmas shopping and all of a sudden my mom says a joke and my brother in law starts laughing really hard the my sister started then my mom and then me. I can not remember the joke but we were maybe laughing like for two minutes. Without stop and those are the kind of laughs that i really like a lot. Then after we were done with all the shopping we got back in the car and one more time but this time it was only for a few seconds.
