Since that post is long enough as-is, here's another fun fact that's actually somewhat fun this time.

By definition, Tetrapoda (amphibians, reptiles, birds, mammals, etc) is contained within the group Sarcopterygii, or Lobe-Finned Fish. That means that all mammals, birds, reptiles, and amphibians, including humans, are actually Lobe-Finned Fish.
