Scooby got his name from a Frank Sinatra song

Originally, Scooby’s name was set to be “Too Much,” but the executives realized that the name sucked.

According to one producer, he was listening to Sinatra’s “Stranger’s in the Night” and loved the part where he sang doo-be-doo-be-doo.” From there he got his full name – Scoobert Doo.
