I use the laughing at myself pretty often, and have no dignity or shame when it comes to sharing the idiocies of my life. I grew up in a family with a very unique sense of humour. Actually, it wasn't very unique — as I grew up in Denmark, it was rather typically Danish, pretty dark and pretty harsh (or so it seems to softies). Really, it just sounds harsh — it comes from a place of love. Based on what you're describing about you and Laurie, you could be honorary Danes! 
Finding a way to include laughter every day is the only way to get through life with a chronic illness with your sanity — relative sanity — intact. And yes, RA does add a lot of funny moments.
Brad,
You made me laugh just reading your article. Your wife's comment had me rolling. On a serious note, you are *so* right. Laughter should not be taken lightly. I beleive it has the ability to heal. Thanks so much for this wonderful article!
