I've heard this a lot.. "Pretty girls hang out with 'ugly' girls so that the pretty girls look prettier." I think it's horsecrap, but I'm going to entertain the idea for just a second. If this is the case, guys, listen up. If you have a pretty friend, stop asking her to introduce you to her friends because most likely, they'll be 'ugly.' If you meet an ugly girl on the street, stop and say "hello" because most likely she will have a hottie friend.
