A meme with multiple layers. The original dialogue is from the Sonic Boom cartoon. In the show, Dr. Eggman complains that his soup is cold and his salad is hot, then exclaims "How is that even possible!?".

They replaced the line "When the wind is low, and the fire is hot," with "The soup is cold, and the salad is hot!".
