The Museum of Tomorrow

As an alien fleet approaches Under, Russell is arrested by Agent Greg and his Future Infractions Bureau for a crime he has yet to commit. The others head to the Museum of Tomorrow to try to find out what crime he will commit but are arrested themselves for planning on breaking Russell out of jail. Gus has everyone speak in past tense instead of future tense so they won't be caught again, and he and Russell escape with the help of Vernon, Loopy, and Populah, and head to the Museum to visit the future. (Note: This is the second—and final—episode in which Bob Wire does not appear, nor do the Frags. In fact, it is the only episode in which none of the main antagonists of the series appear.)
