In real life, the guts and organs are just as unappetizing. "The most disgusting, weird stuff," Barrymore said. "And I have to act like, ‘Mmm,' it's like ecstasy, and I'm just disgusted."

Barrymore said the gross-looking items she eats are dried apples, wet cake, beet shakes, grains that "ferment, so by the time I eat them they're rotten" and "plastic rubber."

"It's not plastic rubber," Olyphant said.

"It is plastic rubber!" Barrymore maintained. "It's an edible plastic rubber. It tastes like latex. It's disgusting."

Olyphant has not tried the TV guts, but said, "I know for a fact you cannot eat plastic rubber."

"But there's an edible plastic," Barrymore continued to maintain.
