Whoever created this deserves a Nobel Prize in Nerd Humor! These Venn diagrams brilliantly illustrate logical operators using Halloween's "Trick or Treat" tradition. Each diagram shows exactly how Boolean logic gates work:
OR: You get either trick OR treat OR both (union of sets)
AND: You only get what's in both circles (intersection)
XOR: You get either trick OR treat but NOT both (exclusive OR)
NOR: You get nothing! (negation of OR)
NAND: Everything except what's in both circles (negation of AND)
XNOR: You get both OR neither (negation of XOR)
The pumpkin faces perfectly match each operation's result. This is what happens when computer scientists go trick-or-treating!
