"Come on Down" because the Price is Right turns 40 years old today (September 4)! It made it's debut on September 4th, 1972 and is the longest running game show in television show in history.

The show will celebrate it's anniversary today by bringing back old contestants and they will show a bunch of old clips. Today's anniversary show will be hosted by current host Drew Carey.

There are a ton of Youtube clips from the show. Check out this one featuring one of the worst contestants of all time. Bob Barker's reaction is priceless!
