|"The Time Traveler's Pig," "Blendin's Game"|
- The film about Quentin Trembley states he was elected in 1837 as the 8½th president of the United States, but there were no presidential elections in 1837. In 1840, Trembley's alleged replacement William Henry Harrison (who had lost in 1836) defeated then-President Martin Van Buren's bid for reelection and became the ninth President of the United States.
- Blendin Blandin comes from the year 207̃012. However, this contradicts the idea that the end of the world will occur in 3012 (according to the Mailbox). This discrepancy might be explained by the fact that year 207̃012 may happen between 2012 and 3012 or in an alternate timeline, or that Time Baby has rebuilt the world since 3012.
- The credits cipher from "Weirdmageddon Part 1," says that Time Baby's particles will take 1000 years to reform, and, because the show takes place in 2012, this would happen in 3012, the year given by the mailbox.
- "Blendin's Game" takes place on July 13th, Soos' birthday, in the series, but in Journal 3 the events of this episode are said to happen sometime between July 23rd and August 25th.
