- Not What It Looks Like: Just like with "Let's Go To The Mall", Barney (and Marshall) mistake Space Teens for porn. Not that you can blame them.

- Rage Quit: Robin puts an end to the Space Teens viewings once they reach "The Beaver Song" to prevent further dirty comments.Robin: No! You don't get to hear "The Beaver Song"! It is a sweet song about friendship, and you guys are being disgusting, and beavers are adorable!
