This one reminds me of a nice story about my grandmother. I recall stopping by for a visit when she was in her late 80's. When using the bathroom I noticed that she had a very large can of hairspray perched on the back of the toilet. I asked her about it, mostly because she stopped worrying and fussing about her hair years before.
She explained that the hairspray was very effective at "shooting down" those darn house flies that tend to bother her when on the john. Try it, it can be fun to watch their little wings sieze up in mid-air.
