At least twice already, they had quit and un-quit "I'm a Celebrity ... Get Me Out of Here!" But the bratty newlyweds, who star on MTV's "The Hills," were seen taking what's presumably their final leave on the Tuesday edition of the NBC competition series only its second night.
"I'm a Celebrity" airs from the Costa Rican jungle, with semi-famous people competing for food, supplies, money for their chosen charities and TV screen-time.
But as Spencer explained, "Super-celebrities don't belong in the jungle. They belong in Hollywood with the paparazzi."
"We're gonna miss you guys," Heidi told the not-so-super-celebrities they were ditching. "But call us when you get back to LA."
Actor Lou Diamond Phillips, TV personality Janice Dickinson and former Illinois first lady Patti Blagojevich are among the nine remaining contestants.
So is Stephen Baldwin, actor and reality-show veteran, who described himself as a nondenominational born-again Christian. Before the Pratts bolted, Baldwin offered to baptize Spencer, who jumped at the chance since his wife is a professed Christian.
And how! "My goal is to be a true disciple of Jesus, a Mother Teresa helping the poor and the hungry," she said, straight-faced.
"Now you're looking at a new Spencer Pratt," Heidi's born-again hubby told America after the ceremony in a picturesque stream.
Soon after that, the couple declared they had had enough, and were getting out of there.
"Let them go off to Heidi-wood along the Yellow Brick Road," muttered Dickinson.
Will that be the last of them? TMZ and Extra were already reporting that Spencer was begging NBC to let him and Heidi un-quit again.
At the end of the hour, viewers were invited to cast their votes to eliminate one of the women contenders (with Blagojevich granted immunity for now). The results were promised for Thursday's show.
"I'm a Celebrity ... Get Me Out of Here!" drew 6.4 million viewers for Monday's debut, according to Nielsen Media Research. It continues through June 24 on multiple weeknights.
