Bob Barker's 90th birthday present is urging one more contestant to "come on down" from the audience on "The Price Is Right."

The veteran game-show host, at the helm of "The Price Is Right" from 1972 to 2007, was invited back by current host Drew Carey on Thursday to celebrate the milestone birthday.

He moved a little more slowly, and his microphone was a little thicker, but Barker fell right back into the groove. The audience gave him a standing ovation, and he joined with Carey in encouraging viewers to spay or neuter their pets — Barker's longtime cause.

To the reception, Barker said, "You folks appreciate the fact that it has taken me a long time to become 90."
