Probably not crispy (original) is a video of an old man with a white beard coming to try roast pork and saying "not crispy", then the shop owner grabbed his beard so he said "crispy", the funny video is a meme video of an old man with a white beard saying "probably not crispy" with a triumphant, confident look, but then still got scared by the shop owner and had to admit that the roast pork was crispy.
