With only the previews to go by, it seems to me that it's one marginally funny joke told over and over and over by various grocery items. Looks like about two minutes worth of censored SNL material.
"LCD humor" probably nails it, since it's Seth Rogen. I'm sure all his work is funnier if you're stoned on his couch listening to him pitch his latest "wouldn't it be funny if...?" movie idea.
I can picture him and his "producer" buddies sitting in the control booth masturbating as Salma Hayek says the f-word at the studio microphone. It's not pretty.
