- Yeah. Listen to this. Dog named in inheritance. Eccentric millionaire Colonel Beauregard Sanders leaves $1 million to 4 relatives and a dog named Scooby-Doo.

- Scooby-Doo had rescued old Beauregard from a fishpond several years before and was remembered in his will.

- Well, I wish I'd remembered not to come along. No telling what's waiting for us tonight.

- Oh, I see you made it. Well, bring the dog and come in.

- The others are waiting inside.

- Yes, sir.

- Attention, everybody. As you all know, I am Cosgood Creeps, attorney of the late Colonel Sanders.

- My partner, Mr. Crawls, couldn't make it tonight.

- Creeps and Crawls? They sure picked the right lawyers for this job.

- Colonel Sanders was a bit odd, and his only instructions were to play this record for you.

- Greetings, y'all! Cousin Simple, Nephew Normal, Sweet Cousin Maldehyde, Cousin Slicker, and my old friend Scooby-Doo.
