Samuel L. Jackson had the words, 'Bad Motherf*cker' in-scripted on his lightsaber during the filming of Star Wars.

The statement is false. Samuel L. Jackson did not have the words "bad motherfucker" inscribed on his lightsaber during the filming of Star Wars. It appears to be a mix-up or a misconception as those words famously appeared on a wallet that Jackson's character, Jules Winnfield, used in the movie Pulp Fiction, not in any Star Wars film.
