I can't believe I never saw this commercial before!  It is not new but it is classic.  Billy Crystal dressed as a turkey and Robert De Niro in pilgrim garb...lol!

You probably wouldn't expect these actors to do a TV commercial in costume but it was for very good reason.  The commercial was aired to promote the Macy's Thanksgiving Day Parade and tourism in New York in 2001 after the 9-11 attacks.
