Calvin kills his "living peanut butter sandwich."
Calvin often eats his lunch next to Susie in the school cafeteria.
The "Foods"
Calvin often lies about what he has for lunch. His many "lunches" have included a thermos filled with phlegm, "living" peanut butter sandwich, and cigar butts. Susie has nearly always gotten revolted at this.
Cafeteria Lunch
Sometimes Calvin gets cafeteria food, which looks mostly the same as his dinner. He combines his "stunts" at home with normal disgusting lunch claims. Unlike dinner, though, he has managed to survive while eating it and it does no harm to him.
