Trivia

After this special originally aired children all over the country sent candy to Charlie Brown out of sympathy.

Actress Cathy Steinberg had almost finished recording all her lines of dialog as Sally when the producers received a phone call from Steinberg's mother informing them that one of Cathy's teeth was loose. Fearing that a sudden lisp would ruin the continuity dialogue, the producers rushed the young actress into the studio to finish recording her lines. Just as Steinberg was speaking her last line, the tooth came flying out of her mouth.

Lucy's signature move - pulling the football away from Chuck as he's about to kick it, causing him to fly through the air and land on his back - was animated for the first time here.

Schroeder plays four songs for Snoopy from World War One: "It's a Long Way to Tipperary," "There's a Long, Long Trail," "Pack Up Your Troubles In Your Old Kit Bag," and "Roses of Picardy."

This is the only special where Pig Pen is shown wearing glasses. You can see them when he is with the other kids at the Halloween party around the apple tub just before Lucy bobs for an apple.
