Serious point about a satirical post:
Wires don't have an inherent propagation delay.
Putting a wire into a practical circuit makes a transmission line, of more-or-less good properties, and the propagation time down that line must be slower than the speed of light in vacuum. Putting the wire closer to a ground plane affects the propagation time down the transmission line.
You can also wind inductors from the wire and make a delay line, of more-or-less good properties, and get an even slower proagation time.
The actual drift velocity of individual electrons in the wire is amazingly slow: this is given by the mobility factors that are important in solid-state device design. The charge-carrier velocities are proportional to the E-field within the solid.
