After Jim kissed Pam and she couldn't admit that she had feelings him, he decided to take a promotion and transfer to Connecticut. He was having a hard time adjusting to the new job. He was sure none of his new co-workers knew his real name; instead, they gave him the nickname "Big Tuna" because he brought a tuna fish sandwich for lunch on his first day.
After Michael found out Oscar was gay, he wanted to know who else in the office was homosexual. Michael was concerned about the way he had to behave, especially after Oscar complained to Toby about Michael using the nickname "Faggy" for a lot of his co-workers. Michael asked Dwight to help him find out who else was gay at work.
Pam hadn't gotten married to Roy because she'd had "cold feet" a few days prior to the wedding. She'd broke up with him, gotten her own apartment, and bought a new car. But since they'd already purchased the food for the wedding, Roy had to come by every day and bring her lunch - chicken or fish. He was determined to win her back.
Michael held an office-wide meeting to discuss homosexuality. He put Oscar on the spot and told him in front of everyone that he should out himself right now. Oscar was clearly uncomfortable, and Angela didn't improve the situation by going on a rant about how wrong homosexuality was. Dwight chimed in and said everybody in the office who was gay should just come out. Oscar said he was the only gay person there. Dwight asked about Phyllis' sexual orientation, but Phyllis said she'd gotten engaged to Bob Vance.
Michael wanted to prove that there was nothing wrong with homosexuality, so he started hugging a reluctant Oscar. He tried to kiss him but Oscar kept backing away. In a very awkward moment, Michael eventually succeeded in kissing Oscar on the lips. It got more awkward when Dwight got up and tried to kiss Oscar, too. At the end of the day, Michael felt he'd taught a lesson about homosexuality to the rest of the staff. Meanwhile, Jan offered Oscar three months paid vacation and a new car if he signed a document saying he wouldn't sue Dunder-Mifflin.
