I'm going to tape an open can of tuna in my friends car under the drivers seat?

[katy313@ymailecom]

it's just a prank, she never locks her car so she can't say breaking and entering and i'm not destroying any property, so would i get into any trouble if she told the police or a teacher? (I'll be doing it at school, that way it'll stink up her car and when everyone gets in her car to go to lunch they'll all be disgusted)
