Fly

This is a "bottle episode," an episode with limited cast and sets produced due to limited budget. The show had spent much of the budget on the building of the superlab, so a low-cost episode was needed.

Jesse talks about a TV show on hyenas that he saw. He says the head hyena was "the Man" and how gross it was that the other pack members had to "lick his junk" to show respect. Either Jesse or the script writer didn't realize that among hyenas the females are actually dominant, including the leader of the pack. They are larger than the males and have other marked masculine physical traits due to a naturally high level of testosterone. If Walter knew that, he didn't bother to correct Jesse's mistake.
