It's poop humor without the poop. it's as basic as humor gets.

For me at least, it's refreshing to see them getting more to what the product does than engaging in euphamism and symbolism. I wouldn't want to see a guy actually squeezing one out on tv, but some barrels rolling off a truck? Funny and clean.

And it's far less disturbing than say the Domino's fudgem ad. He're they're using construction items representing poop to sell a product that helps you poop. There they were using food goo that actually looks like poop to sell you a chocolate dessert that is supposed to be appetizing.
