Kyle, a social outcast, is a big smoker. Cigarette butts litter the floor by his recliner.
Sensing something wrong, he rises, taking an unseen thing with him, and shuffles to the kitchen.
There, we see that the thing is the hollowed-out head of a man, and it is loaded with cigarette butts. Kyle observes his human ashtray's bad shape and tosses it into the trash.
He opens his refrigerator, where another half-dozen heads are waiting. He picks one at random - a woman. He takes his new ashtray back to his recliner, balancing the head on his lap. He lights a cigarette and momentarily holds it to the head's lips. Then he sits back and enjoys a smoke with his new lady friend.
