Oh, I often do this. I think that it's because I spend a significant chunk of my "alone time" lost in my own thoughts, particularly when I'm just walking somewhere, or engaged in some other mundane task. Frequently, my thoughts are completely unrelated to my surroundings, and it's not unusual for me to hit upon something funny. When this happens, I sometimes can't resist the urge to laugh, or at least smile.
I also tend to perseverate on things that I find particularly funny. A couple of weeks ago, my boyfriend S and I were playing Mad Libs on Skype (S is presently on the other side of the country from me). S made a joke relating to a word he had come up with, and his remark struck me as hilarious. After our Skype conversation had concluded, I continued perseverating on his remark, and intermittently laughing to myself for the remainder of the evening. A few days later, S and I were playing Mad Libs again, and S said something relating to his previous funny remark. This prompted me to repeat his joke back to him, pretty much word for word. S was amazed by my level of accuracy in remembering the details of his joke, and said, "Wow, you have a very good memory." Ha! I remembered his joke because I'd been perseverating on it. I still can never remember where I put my keys, or my laundry card, or my credit card. That's probably because, when I put those things away, I'm usually thinking about something completely unrelated to what I'm doing. In some cases, that unrelated something is something funny, something that may render me unable to resist smiling or laughing to myself.
