On the last day of school our senior year... my friend and I went to all 3 student parking lots, the teachers parking lot and the park across the street- hundreds and hundreds of cars. We took yellow window chalk and wrote "00" (for 2000) on every single car. Our school was 4,000+ students. (But, of course not everyone drives.) For weeks you could see the yellow "00"s on cars around town. We are still legends at that school when it comes to Senior Pranks. (see more)
