Marshall's co-worker whom he used to make Lily jealous.

- Ethical Slut: She loves partying and sleeping around. When she found out she drunkenly kissed Marshall, who's married, she felt terrible.
- Foil: To Lily. Both are girls who look feminine but have huge ladette streaks, and are both associated with and romantically interested in Marshall. But Jenkins Really Gets Around and keeps going for new "relationships" with everyone she meets. Lily is a Clingy Jealous Girl who likes the group she's with, and gets really angered whenever one of her friends meets someone else and gets along with them.

- Only One Name: We don't know if it's a Tomboyish Name or she's into Last-Name Basis.
- The Rashomon: Marshall accidentally ends up using this when describing her antics, because what is funny and quirky for a goofy fat guy ends up becoming very erotic and exhibitionist for an attractive woman (taking off your shirt when drunk and smearing jam all over your face).
- Really Gets Around: She kissed Marshall while drunk, and had sex with a stranger in a darkened mail room at the Goliath National Bank headquarters.
- Samus Is a Girl: When Marshall told the gang stories about her antics, they all thought she was a man until they finally met her in person. Justified as Ted really thought Jenkins was a guy when Marshall told how Jenkins "peed out of a cab's window".

When asked for random numbers, Steve calls out the ArcNumbers from Lost which "cursed" Hurley (making this one a literal shout out). Finally, he compares the unlucky streak to being on an island for a very long time, which is how Hurley's character arc ultimately ends.
- Sixth Ranger: Briefly joins the gang once he briefly sheds the curse of the Blitz.
- Yank the Dog's Chain: The episode saw him finally being free from "the Blitz curse"... only to acquire it again at the end of the same episode. In "Gary Blauman", Future! Ted reveals that he still has the curse.
