Pepperoni and pickle sounds roughly edible, assuming we're talking about a sour pickle.
Utter than being an utter heart attack pie, butter and salami with 'double yogurt' probably doesn't taste that horrific, though it probably tastes mostly of yogurt. Which isn't something unheard of on dishes roughly similar to pizza, yogurt is the base of tzatziki sauce and a gyro is meat and tomatoes on bread, sometimes with cheese (like feta).
Popcorn wouldn't be horrific but it probably wouldn't be particularly tasty either.
Everything else in this image is fucking heresy. Why did the turtles like sweet shit on their pizza??
