TripleDent Gum

Tripledent Gum is a brand of gum in Inside Out. At some point in her life, Riley saw a commercial for the company, and its jingle got stuck in her head ever since then. Indeed, the memory of this commercial is one of the strongest Riley has, to the point Forgetter Bobby says it "will never fade".

Much to the annoyance of the Emotions, the memory has a tendancy to come up to Headquarters randomly without being called out. This is in part because the Forgetters love it so much they sometimes send it to Headquarters for no reason.

During the credits, it is revealed that a bus driver named Gary has the same memory, and that it annoys his emotions much more than Riley's.
