circuit diagram for a fire alarm?
if you smell smoke you should see smoke and a fire would be noticeable in a few minutes so if there's no other sign of a fire then you might want to call your doctor and tell him your smelling smoke i don't know if its of any importance but you never know.
A shower? Soap? A washcloth? A FIRE HOSE! Do you EVER wash your underwear? (Forget that, if their brown, just burn them) Luck
