Murphy's Locker room Law

When you select a locker in an empty locker room, the next person coming back to their locker will be right next to yours. If they happen to enter at the exact moment you're putting on your underwear, then their locker will be on the opposite side of you and they'll have to shuffle by uncomfortably close.

Me: (putting on underwear in the locker room)
Next guy: oh hi, I need to slip past you to get to my locker; hope you don't mind.
Me: No problem; it's Murphy's Locker room Law.
Next guy & Me: chuckle chuckle chuckle

Murphy's locker

The likelihood that when you select a locker (usually at gym) that someone will need to access the locker above, next to, or under the one you are using.

Gym Rat One: "Are you waiting for something?"
Gym Rat Two: "Yeah, my locker is below yours."
Gym Rat One: "What are the odds of that considering there are probably 100 in this locker room?"
Gym Rat One: "It's called Murphy's locker. Good workout?"
