The Seniorville Trolley

The Seniorville Trolley is a bus catering to the elderly. It is likely associated with the Springfield Retirement Castle. After Jacqueline Bouvier decided to cut short her wedding with Charles Montgomery Burns, she and Abraham Simpson II boarded this bus.

Behind the Laughter
The scene where Jacqueline and Abraham exit an aborted wedding, go to a bus, and walk to the back of it is a parody of a scene following the same basic narrative between John and Elaine in the 1967 film The Graduate.
