Barker, who hosted the show for 35 years before retiring in 2007, appeared as a guest this week, joining Drew Carey to cheer on people to win big money.
The former host finally got to fulfill one of his biggest TV wishes, inviting audience members to "Come on Down." Many Price is Right fans mistakenly believe the host gets to utter this famous line, but it's actually the announcer's honor.
To celebrate the 9-0 milestone, Barker was given a giant cake and time to help with the show's pet adoption week. Here's to many more years for our favorite Plinko aficionado.
