Imagine that phone call....
DD: "Uh hey Nick, so I got fired again, and I uh...kinda need a job. So how about me coming to join your staff, just like old times! I can coach WR or whatever..."
NS: "Well the thing is Derek, when I first hired you, I didn't realize you were a moron. By the time I realized, we were already in the thick of things, and I liked your personality--you were charismatic, and that helps in recruiting--so I kept you on staff, hoping you'd leave sooner rather than later riding the coattails of my success to get yourself a better gig. Since then, you've firmly established yourself as a moron, so I don't know if I want that on my staff at Alabama."
DD: "But, wait....you hired Butch Jones to get your coffee, and he's a moron too! By the way, I'm taping this conversation so if you don't hire me to do Butch's old job, I'm going to sue you for moron decriminalization!"
NS: "I think you meant moron discrimination. And no jury will buy that. I've hired other morons in the past. Take Jeremy Pruitt, for example. And I got Butch for free, so there's that."
DD: (starts sobbing)
NS: "Fine, you can fetch my coffee...but you have to clean my eyeglasses, do my laundry, and teach proper shower technique too"
DD: "YESSSSSSSSSSSSS"
