"Price is Right" legend Bob Barker is turning the big 9-0 next week ... but he tells TMZ, despite his age, he could still put a serious hurtin' on Adam Sandler.
Barker went out to a pre-bday dinner at Antonio's Restaurant on Melrose last night and told us he's excited about entering his 10th decade ... "I only have to wait ten years and I'll be 100!"
Bob says this birthday is extra special because, "It takes a long time to become 90."
And even though he says he only feels 85, Barker insists he could still recreate that great fight scene from "Happy Gilmore" ... telling us Adam couldn't even take Regis Philbin!
HAPPY BIRTHDAY BOB ... and remember to have your pets spayed or neutered.
