1) Fujioka Haruhi is one of the main characters of the anime series Ouran High School Host Club
that is mistaken for a boy by the school's well... host club and is forced to join them because she broke an extremely expensive vase. She didn't mind that her gender was mistaken though, it's probably because her father is a transvestite.
2) Suzumiya Haruhi is the main character of the anime series The Melancholy of Suzumiya Haruhi
. She is a beautiful, high school girl that is unusually weird and unpopular. That is because she will only accept friends that are espers, ghosts, and aliens. Haruhi also starts a club at her school called the S.O.S. Brigade that has 4 other members.
1) Stop being such a Haruhi Jenna! Unless you really do want girls to start crushing on you!
2) Geez Kevin, you're such a Haruhi sometimes. I'm sorry but I don't think that its very likely that you'll find an alien that will be you're friend.
