Hollowed-out books and the failed secret smoker

The hosts discuss carving books out to hide valuables — hollowed-book safes, hiding spots in toilet tanks and under engine covers — after one host confesses a plan to become a 'secret smoker' by hiding cigarettes in three places when he was trying to quit. The plan failed immediately: smokers can't smell themselves, cheap cologne gives them away, and hiding the habit means never smoking enough to be worth it.
