Hold up, I found different line of Harrison Ford’s from Raiders of the Lost Ark. This makes it so that Han still calls Jabba a “son of a bitch,” but he first laughs sarcastically. Indiana Jones says this in a temple, so there’s an echo. I had to add a reverb effect to the surrounding lines, which I think can be played off as being spoken the same loudspeaker that Threepio is speaking on.
