You never know who your real friends are until they all turn out to be pirates and you have to walk the plank.
You never know who your real friends are until you walk around and count them all at the zoo.
You never know who your real friends are until you're allowed to be a background dancer in their rap video.
You never know who your real friends are until you confess that you slept with her brother who is really your illegitimate cousin who once stole your father's identical twin brother's inheritance.
You never know who your real friends are until you have the facebook.
You never know who your real friends are until the time comes to wrestle in jello. Don't you worry. The time will come...
