A jerk well renowned for his work skill
He's out, the proof is the computer's down Urkel
MC a show via wi-fi
And paid way before we wrap it up like tie-dye
These lines seem to reference the DOOMpostor phenomenon, discussed above — DOOM is doing shows remotely, and still getting paid (in advance, naturally); when he finishes, the computer he was using goes down. His expertise with technology drives the Urkel reference.
Note that DOOM’s namesake, Dr. Doom, was notorious for sending robotic doppelgängers of himself into battle.
