An image showing 6 Venn diagrams with overlapping circles. In first image, both circles and their intersection are filled in with the caption "Trick OR Treat" and depict an image of two jack o'lanterns sitting side by side. The remaining diagrams are Trick AND Treat, Trick XOR Treat, Trick NOR Treat, Trick NAND Treat and finally Trick XNOR Treat and are each filled in according to the logical operator with the same underlying image.
