My dad was watching a football game on TV when profiles for three players came on the screen. The profiles appear under head shots of the players that aren’t pictures, but videos, so they’re moving while looking into the camera (creepy/cool).
Me: Why is only that one guy blinking? Why aren’t the other guys blinking? – Oh wait, that middle guy just blinked. But that other guy is standing so still!
Dad: That first guy is an iguana.
Me: What?
Dad: He’s an iguana, they don’t have eyelids, iguanas don’t blink.

This conversation actually went on for a while but I’ll save you that and end it there.
