It shows that you are
clever, smart fun and down to earth in
ways that a direct claim will not work. It
also makes you seem more
approachable. Don't use humor at
others expense. Don't use off color
humor. Don't use too much self
deprecating humor. This can be
misinterpreted as a lack of self
confidence. Don't worry about making
everyone laugh because you will always
confuse and even turn off some. The
people that get a kick out of your
specific brand of humor will most likely
be fun to be around
