If you're at Baker Street station today or tomorrow (18 and 19 March), and think you just heard Morgan Freeman tell you to "mind the bap!", the good news is you're (probably) not having a nervous breakdown.
To celebrate 150 years in the baking biz, crumpet slingers Warburtons called on the butyraceous-brogued Hollywood star to lay down a series of pre-recorded voice announcements.
Waiting on the northbound Jubilee line platform — temporarily rebranded to 'Bakers Street', and complete with crumpet roundels — passengers will be reminded by Freeman to "mind the bap!" and "stand behind the buttery yellow line", alongside various other bready puns.
Perhaps someone pointed Morgan in the direction of our Baker's Tube Map. Next stop: Mary-Berry-Lebone!
