Trivia: When Ryan (Leslie Nielsen) jumps away from the bus as it gets hit by a train, Ryan lands on a bicycle that doesn't have a seat.

The second announcement is for Dr. Kevorkian to Mr. Simpson's room. In Naked Gun 33 1/3: The Final Insult, Nordberg, who was portrayed by O.J. Simpson, suggest that Leslie Nielsen be given Dr. Kevorkian's home phone number.
