So we call a "flock" of crows a murder. Also, counting crows is a band and murder by numbers is a movie. The joke goes, the band name/concept of literally counting crows is just the movie/concept of murder "flock of crows" by....wait for it...numbers! Counting crows/flock of crows by numbers hardy har funny! I don't know if that helped or made it worse but there is no turning back now.
