Dean Pelton and Annie host an STD awareness fair at Greendale as Troy and Abed compete against each other to see who is the better athlete.
Dean Pelton (Jim Rash) and Annie (Alison Brie) are promoting Greendale's upcoming STD fair, handing out fortune cookies and flyers.
Pierce (Chevy Chase) asks Jeff to double date with him and his new girlfriend, Doreen (Sharon Lawrence), an escort, to the fair later that night.
Dean Pelton decides that Annie should conduct a condom demonstration on an anatomically correct model of a penis center stage at the fair.
Annie, Shirley and Britta try to break into the Dean's office, but as they look at the model penis through the keyhole, campus security walk in and detain the three.
They are brought to Dean Pelton and the school counselor to discuss the incident; Annie accepts that she prefers being uncomfortable talking about sexuality.
During the double date, Doreen tells Jeff that he could do a lot better than Sabrina, and that as men become older, they prefer conversational companionship over sex.
Back inside the fair, Dean Pelton observes that the alcohol served has caused many of the students to be highly sexually aroused.
