Your guests politely try to nudge the pinata away, gently at first. The pest returns. Nudge turns to shove. Shove turns to drop. The beast keeps returning, snarling and snapping.
Drop turns to heave.
Your guests' shotput efforts are leaving dents in the opposite wall, but Kujo keeps coming back. Then with one final Herculean effort, your guests hurl the beast through the window, but like an evil spirit from beyond the grave, heeeee's baaaaack. And then for some reason you've never quite figured out, your guests determine they had better leave to, uh, see if the grass in their lawn is still green. You wonder for a moment why you don't have any friends. As soon as they leave, the pinata from hell finds its favorite resting spot, circles the pillow three times before preening itself into the cutest little ball of fluff.
