[Star Wars] Are there any examples of, or is it even possoble to be, a happy, cheerful, and affable Sith?

Sith are so often portrayed as dark, brooding murder hobos who take themselves and the dark side super seriously. Are there any examples of sith who are wisecracking, cheerful, or laid back, while still evil and self serving?

He sure wasn't affable or cheerful, but Vader was known to make a wisecrack every now and then.

Like that time he told Krennic "don't choke on your ambition" after force-choking him for being too ambitious.
