1-800-GOLF-TIP is a mysterious phone number from the 90's. apparently it was found on a billboard. r/RBI on Reddit investigated- they could not determine the purpose of the number.
Back in the 90s there was this weird phone number: 1-800-GOLF-TIP. After calling it, there's be a looping recording of a man counting from 1 to 10. If you let it go for long enough it would eventually stop. After a while longer a really loud siren-type sound would go.
