Looting a construction site for a cone or barrel and either tossing it at your friend's house or sticking it on their car because you're too cheap to buy them a real gift.
I took a cone and threw it at my friend's window. His dog ran away.
I stole a barrel and put it on my buddy's car. Now it looks like a parking spot.
I grabbed a barricade and stuck it on my neighbor's porch. She thinks it's a new rug.
