OK here's my best/lamest:
I'm driving home from the bar gf in passenger seat, 2 4-lane surface streets intersect at a light in a relatively unpopulated area. GF has her window down... i hear a car revving...
Looking around... I don't SEE anything that would rev on me.. then i hear it again. Again, I don't see s***. no HIDs, nothing that would fit the description of a tuner in any way shape or form.
Light turns green, and the red Volvo 740 wagon next to me chirps the tires and takes off. I watch him go as I bust out laughing, and point out that I wasn't bullshitting to my gf when I said that the ford probe that whipped around a corner I was waiting to pull out from was done to show off for me earlier in the day...
The following day, I removed the spoiler.
