Get  a penny, a nickel, a dime and a quarter. 

Place them on the table in front of you.

Lincoln is on the penny

Roosevelt is on the dime

Jefferson is on the nickel

Washington is on the quarter

Pick any coin and hold it in your hand. 

I will now attempt to use my psychic abilities to determine which coin your are holding.

I see an "n." Is there an "n" in this president's name?
