It was the day of Phyllis and Bob's wedding. Pam was upset because she noticed Phyllis had basically stolen Pam's ideas for her and Roy's would-be wedding. Meanwhile, Michael was very excited to be in charge of pushing Phyllis's father's wheelchair down the aisle.
Michael was trying to offer up advice to Phyllis on her wedding night. She wanted nothing to do with it. Later on, Michael confessed that he had only been to one other wedding in his life, that was the wedding of his mother and step-dad and a very young Michael was so emotional at that wedding that he had peed his pants at the ceremony.
Jim had convinced Dwight that most of the people at Phyllis's wedding were probably wedding crashers. Jim wanted Dwight to help sniff out who were invites to the wedding and who were not. Dwight found himself in hot water when he unknowingly escorted Phyllis's senile uncle out of the party.
As Michael was pushing Phyllis's father down the aisle, her father stunned the crowd and got up and walked his daughter down the aisle himself. Michael was mad at having the spotlight being taken away from him. So in order to get it back, he kept disrupting the wedding ceremony.
Kevin's band, Scrantonicity, was hired to play for the wedding reception. Meanwhile Roy found some time to play catch up with Pam. He told her how impressed he was with Phyllis's taste for the wedding. Pam reminded Roy that all the colors and decorations were originally planned for their wedding.
During the reception, Michael took over the microphone to give a toast to the new couple. His toast was awkward and long, thoroughly annoying both bride and groom. Bob ended up cutting off Michael's speech when he began to tell a raunchy tale from Phyllis' high school days and a struggle ensued. Michael yelled that he hated Bob and left the stage. It was Dwight's job to make sure Michael stayed outside.
Pam watched Jim and Karen dance and left the room. Roy found Pam and told her he paid the band twenty dollars to play their song and then asked Pam to dance. They went outside and shared a private dance together while Dwight and Angela were doing the same thing.
After the dance, Roy invited Pam to leave the wedding with him. Jim watched as the two left and Jim admitted he was very happy to be dating Karen. Meanwhile, Michael was outside sharing a conversation with Phyllis's senile uncle. Michael approached Phyllis to apologize and she was so thankful that he found Uncle Al for her.
