The Pewterschmidt-Griffin Wedding of Lois Pewterschmidt and Peter Griffin has been referenced in many episodes of Family Guy. While not all of the proceedings are known, some portions have been noted.
During a toast during the reception the reception as revealed in "When You Wish Upon a Weinstein", said "What more can I say about my beautiful bride than- milk, milk, lemonade, around the corner fudge is made", and then laughs.
As revealed in "I Am Peter, Hear Me Roar", Peter tapes over the entire wedding video from Lois's vow recitals to when they drive away in the limo. He tapes over it with soft-core cable porn. Lois is appalled because she sent the tape to her Aunt Lil Pewterschmidt at a nursing home.
As revealed in "Play It Again, Brian", when Peter is told he may finally kiss Lois he responds "Kiss her? I'm gonna destroy her!"
Peter tries to sell Lois' wedding dress to another young woman in "Tea Peter".
Peter recalls a half-Persian chick named Flora dancing with Lois' cousin at their wedding and uses the memory for a fantasy to make love to Lois in "Valentine's Day in Quahog".
Peter reports in "Underage Peter" that "Jimmy Crack Corn" is their wedding song.
When Lois locks Peter and the guys in the attic in "A Lot Going On Upstairs", they destroy her wedding dress by defecating on it in order to force her to let them out.
According to "Take a Letter", a week before their wedding, Peter wrote to another girl that he was involved with named Gretchen Mercer and told her that he wasn't sure about going through with the wedding. When Lois finds out, he admits that it was because he was scared as well as being hated by her parents. She admits that the reason she is crying in her wedding pictures is that she was scared as well, but they are both happy to be together.
