Who voiced the M&M's in this iconic Christmas ad?

(NEXSTAR) — Christmas is surrounded by traditions. Whether it’s hiding a pickle ornament in your tree, replaying that specific Mariah Carey song on repeat, celebrating Festivus, or some other practice rooted in cultural or societal history, there are any number of traditions you can count on this time of year. 

Among those is the return of a commercial released nearly three decades ago.

Titled "Faint," Red M&M and Yellow M&M are seen walking into a living room to put out red and green M&M’s.
