uses for the plank in your eye

You could start a club. The National Association for People with Eye Planks (NAPEP).

Alternatively, depending on the size of the plank, you could use it as an actual club.

You could take up golfing, developing a very unusual swing, bringing the plank down and whipping it around to send that sucker 310 yards down the fairway.

Or you could take up carpentry. Always have a 2x4 handy whenever you need one. 

You could make a national holiday to raise awareness for people with planks in their eye. 

Or you could, you know, take it out. 

Thank you. Let’s have a great day.
