Take the epic Cinderella-story scene with Bill Murray swatting flowers and announcing to himself. The script merely called for Carl Spackler to be in front of the clubhouse swinging a club. Ramis huddled with Murray and asked if he'd ever talked to himself, pretending to be an announcer covering the finish of an event. Ramis had done it as a runner to push himself to finish a workout, and as soon as he mentioned the idea to Murray, the fellow Second City alum knew exactly what the director had in mind and ran with it.
