Abraham who?

Okay so lately my 4 year old has been on a role! The other day I cashed in my lottery ticket ( hey it supports the schools right? ) and received my 5 dollars. My son was holding it and I asked him who the president on the front of the bill was. He replied " Oh that guy that is Abraham Jenkins "! I said " well you are right! " Later on I tried teaching him Lincoln, but it still comes out Jenkins :)!
