This thread is great!
When you are a man, home alone for a weekend because your wife is out of town and kids are at grandma and grandpa's house, and you need to get something from the garage....
Don't go into the garage late at night, in your underwear, when it is -10 degrees outside and let the door close behind you, then realize that the door locked from the INSIDE. And then further realize that the front and back doors to your house are also locked.
You will find out that you'd rather rip the doorknob out of the door, shredding it to pieces, than to knock on your next door neighbor's door at midnight in January, in your undies. :D
