Circuit Diagram
[In the upper left corner there is a map scale, labeled with 1 mi (1 km).] [Underneath the scale is a circuit diagram with the following items connected:] An antenna symbol. A blender. An Arduino, labeled with "Arduino, just for blog cred". A chip, labeled "Most expensive chip available". A symbol for an inductor. A pattern that looks like a highway cloverleaf. A battery symbol (with the + and - symbols on the wrong ends) with a value of √2V. A resistor symbol label "120Ω or to taste". A switch that is labeled "glue open". A transistor with two emitters, one P and one N, and no collector. A jar of scarab beetles. A resistor labeled "brown blue orange". An unlabeled resistor with a center tap. A capacitor. A diode. A ground. An inductor. An another inductor. The two inductors and ground are all covered by a "solder blob". A "666 timer" that has pin 5 going into a question mark. A compass rose. A battery, labeled 50V, with grounds on both sides. A long horizontal wire that is labeled "pull this wire really tight". An AC source that is labeled 240V, shorted out, with a label on the short "Omit this if you're a wimp." An inductor that is labeled with "11kg". A Batman symbol. A squirrel. A wire that is labeled as a distance 3/8". A 50V battery. A frowny face. A vertical wire with a 90 degree bend labeled "caution". A balloon. An inductor symbol with a line on the bottom edge labeled as "warm front". A resistor labeled "ë". An electric eel. A capacitor. An unlabeled resistor. A gob of hot glue attached to a chip with an inverter hooked to an XOR gate, both with feedback into each other. A neck strap. A bridge rectifier labeled as "Moral rectifier". A bottle of magic smoke. A fishing bobber. A broken wire labeled with a question mark. A vertical wire labeled with "electrons single file". A switch labeled "Hire someone to open and close switch real fast." A contact labeled "touch tongue here". A resistor labeled "5Ω (decoy)" with only one terminal connected. A methyl group attached to a wire. A complex mesh of 1Ω resistors labeled with "Oh, so you think you're such a whiz at EE201?" A wire labeled "electrons single file". A wire bent in a U shape with an upside-down ground on the end. A flux capacitor with the bottom wire labeled "I-95". A wire labeled "yarn". An arena with two diodes going in and one leaving. An anode labeled "Bury deep, but not too deep." A motor labeled "vibrator". A resistor with a value of π. A 500V AC source. A wire that leads out of frame with a label "to center of sun". A 55 MPH speed limit sign. An SR latch (flip-flop) labeled "may use an actual sandal instead". A holding pen. A wire in a knot. A resistor labeled "8mm". A resistor symbol labeled "not a resistor; wire just does this". A motor symbol labeled "to scale". A tangled mess of wires connected and jumping over each other. A photo diode labeled "tear collector". A wire in the shape of a ECG. A light bulb. A capacitor-looking symbol labeled "3 liters". A resistor labeled "yes". An unlabeled inductor. A resistor with a question mark as a label. An inductor labeled "Take off shirt while wiring this part.  Ooh, yeah, I like that." A ground symbol immersed in a beaker of holy water.

Another fine example of nerd sniping , as mentioned in the title text.
There are pieces of circuit diagrams, road maps, chemical diagrams, and other things all mixed in.
