Okay. Well, I learned back in high school that when you really don't know what you are doing, and you're barely scraping by, you're a 'D' student."You want to go forward, what do you do? You put it in 'D.' When you go backward, what do you do? You put it in 'R.'"Then, with another chuckle, he added: "I'm just sayin' that's not a coincidence."
And when I watch football, it seems to me that the job of the 'D' is to stop all forward progress.
And when I go to the movies, 'R' is for adults.
Or, as Question the Culture puts it:
Well sir, if you've driven to the edge of a cliff, R is exactly the gear you want to be in. And no, it's not a coincidence and it's not funny.
