Carolla suggests installing a $3 deadbolt on your master bedroom door. Although the lock does not have the strength to keep out someone helbent on breaking in, it stalls them and gives you time to move. There are also more practical reasons for doing this.
"It's not going to stop a crazy junkie from goin' Kool Aid Man and puttin' his shoulder through it, but it will stop the kids from walking in on mommy and daddy, uh, making that funny shape," Carolla says. "How many kids have been traumatized by walking in on their parents doing god knows what."
If installing a lock, which requires 20 minutes and a screwdriver, saves billable hours at the shrink, it's a great investment.
