Trivia: On the picnic blanket, there is a dish of ice-cream with a cherry on top. Next to the ice-cream you can see a jar of "Frisby Pure Jam" - a reference to the Warner Brothers director Friz Freleng.
Continuity mistake: When we see a man and woman sitting by a lake, the plate of pancakes on the picnic blanket moves from the left to the right between shots.
