According to the on-line edition of the Merriam-Webster dictionary, Humor is:

 

a : that quality which appeals to a sense of the ludicrous or absurdly incongruous

b : the mental faculty of discovering, expressing, or appreciating the ludicrous or absurdly incongruous

c : something that is or is designed to be comical or amusing

 

Subsequently, their definition of 'Funny' is:

 

a : that quality which appeals to a sense of the ludicrous or absurdly incongruous

b : the mental faculty of discovering, expressing, or appreciating the ludicrous or absurdly congruous

c : something that is or is designed to be comical or amusing

 

Well, what we've done is combine the two into one simple definition - 'something that makes you laugh or smile.' While this is a little broad, we feel that it encompasses all areas of what humor is, from the always classic Knock-Knock joke to an old episode of 'The Honeymooners' or 'Barney Miller'.
