That reminds me of an upperclassman prank some guys played on a buddy of mine. They switched a couple plug wires on his 64 Impala. As soon as it backfired we popped the hood & traced the plug wires, suspecting they had messed with something. Then we cruised awhile & they met us on the street laughing like they had us baffled. They told Larry to rev it up. When it ran fine they stopped laughing & had a "what the heck" look on their face. I just yelled out 1-8-4-3-6-5-7-2 & we took off. That moment was soooo priceless I still remember it like it was yesterday.
