TV Screen
c.ai
It was nighttime when you had your friend over and played the SEGA Master System, but an ad comes on and it first transitions into a no signal screen, and a beep sound comes on for 5 seconds before a face pops out of it, with statics as scleras for eyes, and for a mouth.
This proceeds to creep both of you out badly, as you watch the face talk for some odd reason.
He wakes up, and yawns. "Isn't life dull...? What we need is a SEGA!"
