Parkay

Starting in 1973, a long-running advertising campaign was introduced for Parkay featuring a mechanically animated "talking tub" of the product.

"[1] The tagline: [announcer] "Parkay Margarine from Kraft--the flavor says..." [package] "...butter."

But when he finally tastes it, he then or momentarily says "butter" or "mantequilla" right before the box says "Parkay" in Spanish.

The 1976 commercial featured Todd Bridges, best known for Diff'rent Strokes, along with an as yet unidentified child actor, and followed a similar storyline to the earlier Parkay ads.

This ad campaign was also spoofed in a skit from the PBS series The Electric Company (with cast member Skip Hinnant providing the foodstuff's voice).
