The new animated short, "Big Box Mart," features an "unsuspecting consumer" who loses his highly skilled factory job because the work is being transferred to a lower-wage economy overseas. The worker ends up as a janitor at a mega-retailer. "Big Box Mart" debuted late Thursday during NBC's "The Tonight Show with Jay Leno." Shortly after that, at 9 p.m. PDT, the animation became available on MSN Video and at JibJab.com.
