Marshall is annoyed when Lily doesn't believe that his female coworker, Jenkins, kissed him. Meanwhile, Ted's college kids introduce him to a drinking game they've invented out of Robin's pre-morning news show.
This episode provides examples of:
- Beware the Nice Ones: When Jenkins tells Lily about kissing Marshall (confirming that it actually did happen), Lily snaps and beats the crap out of her.
- Broken Record: Invoked by Robin to kill the drinking game.Robin: If there are any college students watching: butum-butum-butum-butum-butum-butum-butum-butum...
- Hold My Glasses: While Jenkins is apologizing for kissing Marshall, Lily calmly starts handing her purse, scarf and earrings to Barney to prepare for beating the tar out of Jenkins.
- Honor Before Reason: Ted and the students know Robin is baiting them when she's saying "But, um..." rapidly. But they drink because "it's the rules." They all have a mssive hangover the next day as a result.
- Incredibly Lame Pun: When Ted's students invite him to play the Robin Scherbatsky Drinking Game with them.Ted: Well, what can I say, but... "but-ums" up! [long silence] Can I still come?
- Last-Name Basis: Jenkins's first name is never revealed.
- No-Holds-Barred Beatdown: Lily delivers one to Jenkins.
- Out of Focus: Barney's role is reduced in this episode due to Neil Patrick Harris directing.
- Pronoun Trouble: Played for laughs. Marshall neglects to mention Jenkins's sex/gender when he first tells Lily stories of Jenkins's exploits, so when she thinks Jenkins is a man, he avoids referring to her with pronouns to keep up the illusion.
- Too Dumb to Live: Ted and the students could have avoided drinking when Robin began using "But, um..." more, but blindly follow the rules of the drinking game instead.
- Toplessness from the Back: Both the male and female versions of Jenkins.
- Verbal Tic: Robin's tendency to say "But, um..." while conducting interviews becomes the center of a college drinking game.
