Uh, one year I decided to wash my hunting clothes before going hunting Sunday afternoon. My family and I sat down for Sunday dinner after church.
We started to smell something really bad after a few minutes. I checked all the shoes; nope nothing there.
Then I realized I had put my clothes in the dryer (which was vented into the crawl space under the kitchen addition). Went down and checked dryer. Yup, broken bottle of urine in cargo pants pocket.
My wife was not a happy camper. Fortunately bleach took care of it, I guess the cotton pants absorbed all the liquid.
