Anything that brings upon a smile on your face and makes you happy and excited is funny. There are no particular guidelines to categorize something as funny. It is a very subjective thing. You may find a prank like pulling the chair very funny but the other person may not. Something that makes you laugh your heart is funny. Sometimes things can be funny because they were expected to be like that or sometimes because they were not expected to be like that.
