One theory is that Pretzel Logic is about time travel:
Steely Dan FAQ author Anthony Robustelli describes "Pretzel Logic" as a bluesy shuffle about time travel.[6] Fagen has stated that the lyrics, including anachronistic references to Napoleon and minstrel shows, are about time travel.[7][6] According to Robustelli, the "platform" referred to in the song's bridge is the time travel machine.[6]
