Ad Age’s weekly chart lists the top 10 viral videos from last week. A top new debut is a viral campaign for Butterfinger candy starring Seth Green, entering the chart at number two with about 1.3 million views. The number one video for the week is again Volkswagen’s street art experiment where the carmaker turned a subway staircase into a foot piano. It got well north of 2 million views.

The best video this week has to be the local TV ad that hit the chart at number nine but still made Ad Age s headline. The spot for a dealer of foreclosed mobile homes tries tongue-in-cheek candor to sell the goods. It’s produced by Rhett & Link, a pair of independent North Carolina filmmakers gaining a following for producing local ads with heavy doses of campy comedy.

Ad Age’s chart includes number of views for the week and percentage change in views for videos that stayed on the chart. The list is compiled by Visible Measures.
