As the witness goes on to explain in the Reddit post comments, Murray's sly fry thievery "[g]ave everyone in the restaurant a good laugh," you know, because he's freaking Bill Murray. However, Murray did not go so far as to dip the fry in any sort of sauce before eating it, in case you were wondering.
Perhaps unsurprisingly, the new photographic proof has inspired at least one other Bill Murray french fry snatching victims to come forward. As one commenter said, “He did this to me at In & Out in Burbank 4 years ago. No one believed me. This post is my own proof that he does in fact do this.”
Well, there you have it, folks. Bill Murray is out there and no french fry is safe.
