A perverted high school janitor. The kinds of janitors that are named Chuck, and, at football games, are also known as "Sergeant Chuckles" because of their undying school spirit. Most likely graduates of the same high school, but 30 years previous. Often known to compliment young female students by saying, "You look just like Jamie Lee Curtis! She's my favorite actress! I think she's really pretty!", or something of the like.
"Oh look, it's Sergeant Chuckles, jumping and cheering on the field with the cheerleading squad again. What a huge surprise..."
