Every REAL man knows that you only need to know how to use the two most important things in your toolbox.
Duct Tape and WD-40
So listen up and learn something.
If it moves, and it ain't supposed to - use the Duct Tape.
If it don't move, and its supposed to - use the WD-40.
Don't take no rocket scientist to learn that.
One big hammer is also needed.
