Mr. Warbucks was a business mogul who was signing a deal with the company Chazz worked at.
He had the misfortune to arrive at their corporate headquarters with Chazz to sign the deal when Poncho and Boomer arrived on a mission to get Chazz fired so he could become a garbageman. After Poncho realized that Chazz would no longer be able to pay for his food, he and Boomer drank the whiskey they were going to use to frame Chazz, and became intoxicated. Poncho started whining about how he just wanted to spend time with his master, and Mr. Warbucks remarked that it sounded like there was a little dog in Chazz's office who really loved his master.
