Hmm... I usually can tell if a deaf person is faking its laugh. I know what a canned laughter is, many TV sitcoms use laughter tracks. Not as common as it used to be though.
Sometimes, they even captioned these parts.
I would use the "HA, HA" sign. One or both hands, H-shape with thumbs up, flicking back and forth. Appropriate facial expression, of course.
