Taking a cone or barrel from a construction site and either tossing it at your friend's house or sticking it on their car like you're doing it for fun and no one cares.
I grabbed a cone and tossed it through my friend's window. His cereal was covered in paint.
I stole a barrel and put it on my buddy's car. Now it looks like a mini warehouse.
I took a barricade and threw it on my neighbor's porch. She thinks it's a new chair.
