There's a Wal-Mart commercial in a museum that first shows mannequins of various eras (stone age, middle age, etc.) Then we see a woman frozen in shock at seeing how low her bill is at Wal-Mart while her kid tugs on her pants and asks if they can go now (it might just be in Canada).
Yeah, that's my favorite of the series. There's another one where a camera on the 6PM news keeps tilting down, with the cameraman frozen in shock just like the lady over his Wal-Mart receipt. I think the series may only be running in Canada.
