It's a Fish, It's a Bear, It's A... Bird?

Me (to my co-workers): Did you know penguins are birds?
Laur and Jon: Yeah
Laur: You didnt know that?
Me: I think I did, but it just strikes me as odd.
Laur: They're birds. They lay eggs.
Me: Yeah but we lay eggs and we're not birds.
Laur: (silence)
Me: Wait, I mean, reptiles lay eggs, they're not birds.
Laur: But reptiles are closer to birds than you think.
Jon: Some reptiles have live birth.
Me: Well, alligators and turtles lay eggs; they're not birds. Ducks lay eggs. Oh wait, they're birds.
Laur: Did you know the next animal on the list to becoming extinct? The polar bear. Do you know why?
Me: Because its a bird, too?


I'm having more problems than you know with this whole bird thing.
