Hefty wanted a campaign that would separate themselves from their competitors with humor and quirk and for customers to remember the bags’ standout feature, their durability.

Memorable, weird, and fun, MorrowSound’s “Hefty, Hefty, Hefty (Wimpy, Wimpy, Wimpy)” chanting became the audio signature that Hefty would use for decades. The theme is so iconic that it was revamped yet again this year for Hefty’s current advertising campaigns.
