Clams Casino?

Won’t the pack be covered in mayonnaise?

Does this have anything to do with the #BringBackCLAMONAISE campaign from last Black Friday?

The Hellmann’s Mayonnaise Corporation is a weak, cowardly excuse for a company that has ceded control to feckless dinosaurs who wouldn’t know delicious mayonnaise if it was blasted into their mouths with a mayonnaise cannon. If you want to get anything done in this world, you have to do it yourself. Hellman’s can #eatmyclam.

So, who’s that adorable little clam on the jar?

That’s Clambo, the fun-loving mascot of Clam-O-Naise®. He likes surfing, clam bakes, and is a strong supporter of Catalonian separatism.

Will Clam-O-Naise help me become a better person?

We asked ourselves this very question while stranded on a boat in the north Atlantic for three months in 1978. Our motor had broken down, and we were struggling to repair it in the harsh winter cold. We were down to our last jar of Clam-O-Naise® and had nearly given up hope when we made a bold and tangy decision: instead of eating the Clam-O-Naise®, we poured it into the smoking motor. Unorthodox to be sure! But freshly lubricated, our clamboat roared to life, and we soon arrived safely at harbor. The experience left us humbled, but it also taught us a valuable lesson: when times are tough, don’t be shellfish—pass that Clam-O-Naise®!

Where is Clam-O-Naise made?

Clam-O-Naise is manufactured in cool, creamy Seattle. But on a more spiritual level, Clam-O-Naise is made wherever people cry out to the Heavens, yearning for tangy redemption.

Is this real?

It’s all real. The mayo is real. The card pack is real. The prizes are real. Clam-O-Naise® is one of the last bastions of truth in a post-truth world.
