Knuckle Theory

A theory used by measuring the number of days in a month. If your index finger touches your knuckle of your hands, the month has 31 days, while if you touch the skin of your fist, it has 30 (with the exception of February).

Scott: Dude, how many days are there in August?

Dave: 31.

Scott: Isn't it 30?

Dave: Use the Knuckle Theory.

Man's Knuckle

When a man shows his knuckles to other guys, he doesn't show them like a girl-he puts them into a weird fist like a real man does!

He shiwed everyone his Man's Knuckle.
