Transformers Tooth Tunes
From Teletraan I: The Transformers Wiki
Transformers Tooth Tunes is an electric toothbrush marketed by Hasbro that plays a two-minute remix of the original G1 Transformers theme song by sending "sonic vibrations" through the user's teeth. The sound quality isn't perfect (as you could expect from a toothbrush transmitting soundwaves through your jawbone), but it also features some Peter Cullen soundbytes as well.
