At the start of the film, Michel Bentine gets on a number 22 bus going to Knightsbridge, but gets off a number 44 going to Peckham.
When Michael Bentine arranges to meet Suzy Kendall at the River Boat, they are in St James's Park, close to Buckingham Palace, and they agree to meet in 30 minutes, yet when they meet they are near Putney Bridge, a distance of over 4 miles and neither uses any transport to get there.
