Brian and Stewie travel back in time to January 31, 1999 and witness the events that took place in the very first episode of Family Guy, "Death Has a Shadow".
Did You Know?
During their first trip back to 1999, Stewie makes note of two production errors that occurred in the pilot. The first was when Peter's eye goes over his nose when Lois reminds him about the time when he got drunk at church. The second was that, when Peter and his friends are drinking at the stag party and watching TV, the TV isn't plugged in. See more
One Brian wonders how the 9/11 vote can have an odd number of votes since all of the Brians and Stewies are traveling in pairs. One pair brings Peter along and we see Peter voting, thus the vote tally would normally be an odd number. But Peter actually votes twice, so the total should still be even. It turns out though that one of the Brians is dead and couldn't vote, so an odd tally is correct. See more
