Have you ever heard the name Curtis DelRay?

My dad had his 40th Birthday in the late 80’s. During the party (which was filmed, I was like 6 or so) someone called the house, and asked for Curtis DelRay. (pronounced Dell Ray) My dad thinks it was a joke, but doesn’t recall who Curtis DelRay was supposed to be.

My question: Any idea who that was making fun of?

Also, How would you spell the name sounding like Dell Ray?
