Just before Phineas is forced to box, Jeffrey activates the Omni so they could escape. When the Omni is activated, Bogg is wearing boxing gloves. During the corresponding travel-through-time sequence, however, Bogg is no longer wearing the gloves.
Jeffrey says that the attack will happen at 7:55 am, but when Bogg and Jackie are in the radar room where the clock says 7:50 Bogg says they have 10 minutes left. It should have been 5 minutes.
Jeffrey is wearing his pirate hat and vest when he leaves 1798 and is still wearing it when he lands in 1815, but is not seen wearing it during the time travel sequence in between.
Bogg mentions that he was a pirate before he became a Voyager, thus explaining where he got his clothes.
When Babe is preparing to bat against Phineas for the first time, the camera flashes to Jeffrey for a couple of seconds. This scene is reversed, as indicated by the reverse lettering on the uniforms of the players behind Jeffrey.
Bogg has a short memory. When Jeffrey mentions that Benjamin Franklin was an ambassador to France, Bogg remembers that that was where he met him. He forgets that he and Jeffrey just met Franklin in the previous episode.
The episode implies that Jeffrey and Sam's adventure was the inspiration for Mark Twain's "Tom Sawyer".
