A man runs to catch his departing train. Once on board, he realizes he needs to use the toilet. He searches through the carriages, but all the toilets are either occupied or out of order.
He considers getting off to use the station's facilities, but just then, the conductor blows the whistle for departure.
Unable to hold it any longer, the man opens a window, sticks his backside out, and begins to relieve himself. Moments later, the loudspeakers announce:
"The 9:37 train to Leeds is departing from platform 4. Please do not lean out of the windows—especially the bald gentleman with a cigar in his mouth."
