I had a bit of a laugh when I saw this one... It's a classic Burger King commercial from what looks like the 80's. I'm only guessing, but based on the funkadelic music, and the wierd hairstyles, I'm pretty confident that's when it's from. Makes me want to throw on a pair of parachute pants and Oakley Frogskins! But what gives with them ploughing their car into the Drive-Thru sign? Don't think they'll get their meal any faster by doing that...
[UPDATE] Seems that this particular commercial was one of the first commercials to use a popular song as part of the TV campaign. Here's a excerpt from a Wikipedia entry
The use of previously-recorded popular songs in television advertisements began in earnest in 1985 when Burger King used the original recording of Aretha Franklin's song "Freeway of Love" in a television advertisement for the restaurant. This also occurred in 1987 when Nike used the original recording of The Beatles' song "Revolution" in an advertisement for athletic shoes. Since then, many classic popular songs have been used in similar fashion
