So remember this all you dumb plow boys! You need to stick to farming! Abraham Lincoln needed to stick to splittin rails!

***
Not to mention those dumb farmers George Washington and Thomas Jefferson.

A well known anecdote in this regard can be found here, among many places: http://grantian.blogspot.com/2009_08_01_archive.html

Refused a room because of his rustic appearance by an innkeeper who subsequently learned of his error and sent an apology by messenger, Jefferson replied:

“Tell the innkeeper that I value his good intentions highly, but if he has no room for a dirty farmer, he shall have none for the Vice-President of the United States.”
