Dean Pelton (Jim Rash), dressed as a woman from a black & white TV serial, announces that there will be an old-fashioned sock hop held in the cafeteria, as a Sadie Hawkins dance — in other words, a distraction while the CDC confiscates the drinking fountains on the same day.
He gives her sincere advice about never backing down, though it appears that a reference from Britta also makes him realize he lost a lot of money to Bernie Madoff.
Jeff (Joel McHale) finds Britta's Craigslist advertisement asking for Sophie B. Hawkins, or an impersonator, and arrogantly tells her that he "appreciates" her commitment to the lie (from his own legal background, he can relate) but it's time for her to admit the truth and accept the mocking he and the group are waiting to bestow upon her latest "Britta'd" before it becomes a full-on "Britta-strophe."
The two grow closer, but Abed is so caught up in his scheme that he accidentally hurts her feelings when he fails to recognize a romantic moment.
Toward the end of the night the students chant for Sophie B. Hawkins, and Britta takes the stage to admit that the singer will not be coming.
Abed interrupts the performance and professes that his simultaneous dates was wrong and that he would rather spend more time with Rachel, who has now come back to the dance.
Pierce reveals to a surprised Jeff that he arranged for Hawkins to appear, through his moist towelette company's bond with her from when it supplied the Lilith Fair.
