Bob Barker returns to 'The Price Is Right'

Who saw that coming?

On Wednesday's "The Price is Right," legendary game show host Bob Barker made a surprise appearance on his old show in honor of April Fools' Day. When current host Drew Carey was introduced, the doors opened to Barker instead.

And the audience went crazy.

"I am here because I was selected by 'The Price Is Right' to be their April Fool ... I know the world is full of fools, but I am a carefully selected fool," Barker joked.

This "carefully selected fool" began hosting "The Price Is Right" in 1972 until his retirement in 2007. The special April Fools' appearance is his first since his 90th birthday celebration in December 2013.

After his overwhelming welcome, Barker's appearance managed to get even more exciting.

Before welcoming Drew Carey to the stage, Barker hosted a segment called Lucky $even in which his contestant—named Mary—happened to win a brand new SUV. Mary also took home a story she'll be able to tell forever.
