Dirty little tricks...that I might add help keep me sane. I know the following pranks are stupid, but I do go to sleep at night with a smile on my face most of the time.
One of the things I like to do when my "true-believing" wife leaves her new "study aids" and stuff on the kitchen table, is to take a few of them and burn them in the stove. Funny, she never seems to miss them. (I just made about 25 percent of her tracts go bye bye.) Another good one, is to take her new "book study" book, and carefully cut out a page or two in the middle.
Stupid? Yes. Fun? You bethca.
