My pants come off as soon as possible when I get home, and the neighbors know to call before they come over for just that reason. So anything I do in the evenings I generally do pantsless. That includes taking the garbage to the curb, although I at least wait until after dark. I've also been known to garden in my kilt, very comfortable.
As for risking burns, I was in my boxers boiling some starter wort on my heated stir-plate and shattered some glassware, got second degree burns on my leg.
