I don't think you should be punished but I do think you should have to pay the 1.25$ for your half of the new antenna. You shouldnt touch his antenna just for the simple fact that you might get blamed for something. Oh, shit, thats right, you did touch his antenna and you got blamed for something. Lesson learned.
Talk to the owner of the car, tell him you'll buy him 3 new antennas so he can have spares if anybody else bends his antenna, and talk to the owner of the bowling alley and have the owner of the car talk to them with you so they know you apologized and had no cruel intentions. And then both of you can jump pete because hes a dumbass. Then steal his weed, and smoke it.
