It would have been a fine "how do ya do" if the timing was right. He overestimated my enthusiasm to open the door for some vagrant attorney hooligan working a caper.
That could never beat the time one summer in high school when a carful of my buddies happened to pull up next to my Dad's car at a stop light. They motioned for me to roll down the windows and they threw a string of lit firecrackers into the lap of a pal sitting in the front passenger seat. He looked like he was in 3X speed twisting and turning from the pops. That'll get your attention and make your eardrums bleed. We were angry, shellshocked and laughing simultaneously. That was a fun vaccuum job as well.
