In the next round, Susan mistakenly uses the name "Rosa Park" without an S on the end.
Susan Taylor says St. Augustine was founded in 1519, forty-two years before the English settled Jamestown. That's numerically wrong since Jamestown was founded in 1607, eighty-eight years after St. Augustine.
Another omission in the Luther comic strip balloons. Lilly says, "Oreo, look!" and Oreo says, "Lily, look!" But both of the balloons have the single word "Look!"
Remembering the backwards universe (called Back-a-Land), Henry laughingly says "Stop! Noise!" Of course, Henry meant "Start! Noise!"–the command Willie made to tell the Back-a-Landers not to fight them.
The Outerscope I kids find the door to get back to their universe: it's a plain door with the knob on the right side. But when the kids entered in the episode Where is the Door?, the dark side of that door had its knob on the right side. This meant the door knob should have been on the left side of the door discovered in this episode.
At the start of the Outerscope I segment, the crew follows the Syncovek family's directions backwards. Edgar tells Willie to "Hang a right" because the directions go left. But if you saw the directions in the previous show ("Mamavek Makes an Offer"), you saw the first turn in the directions from Technovek to Earth was a right turn.
Earth is rotating in the wrong direction (clockwise) early in the Outerscope I segment. It's a mistake NBC News would commit a few years later.
In the Luther comic strip, Pee-Wee says a line that does not have a balloon on-screen. He says "Is Hardcore?', then "Mary Frances?", then "Lilly?" All but "Lilly" are written in a word balloon.
