"Tone your jaw" with a silicone plug you jam in your mouth

Something I typed in on the Internet today resulted in me subsequently getting the above advertisement for a "portable jaw toning instrument."

The algorithm has scented my blood and is certain I will buy a three-inch silicone mouthplug, to remove my nasolabial folds.
