After Rosco deputizes Bo and Luke in 'Deputy Dukes' and promises that they'd be the only three to know...
Rosco: "I gave you my word, didn't I?"
Balladeer: "Now, about Rosco's word. He has to have somebody else call his dogs...because they don't even believe him anymore."
It's from 'Goodbye, General Lee' in season 4. After Rosco tells Boss that he took care of the General, the conversation is:
Rosco: Listen, Boss, I want a raise now. I want more than 50% of my 50%. Come back.
Boss: I'll give you a raise. I'll give you a 50% raise. I'll give you 50% of 50% of 50%. How about that?
Rosco: Well, that's better. I got him just where he wants me.
How about the time ( again....can't remember the episode) when Boss was double dealing Rosco ( like he always did) and Rosco thought he was getting the better end of the deal and he said,. " I've got him just where he wants me." A statement like that can bend your brain! LOL
I can't remember the episode but it's ...oh wait ......." Two Too Many Roscos". that's it! Rosco: OK....this is a kidnapping, right? Bad Guy: Believe me sheriff, you're not being kidnapped. We just sort of ....borrowed you for a little while." Rosco: Ohhh.....that rattles my slats! ( one of the best lines of all time...used it a few times myself!) You don't borrow a human being....you borrow a cup of sugar maybe....kee kee"
