OK, my parents had a Blue datsun 610 wagon that could be driven to lug the motor, like 3rd gear doin 25mph, and we would floor it. the longer you did it, the bigger tha Bang! It would take about three seconds. We could time it to scare the CRAP out of anyone. My demented buddies always wanted to do it to old people, but I can honestly say I never did. It would suck to give an old timer a heart attack for a stupid joke.
Couple of years later it happened to me. these kids blasted one right next to me. Whatever. they were laughing, just like I used to. Turnabout is fair play. I had to laugh about it, even though my kids were freaked.
