During a convention interview, star Glenn Howerton was asked why his character was named Dennis, whereas Charlie Day and Rob McElhenney's characters are named after themselves. Howerton responded by saying that he wanted to distance himself from his character as much as fucking possible.
As your leader, I encourage you from time to time, and always in a respectful manner, to question my logic. If you’re unconvinced that a particular plan of action I’ve decided is the wisest, tell me so, but allow me to convince you and I promise you right here and now, no subject will ever be taboo. Except, of course, the subject that was just under discussion. The price you pay for bringing up either my Chinese or American heritage as a negative is I collect your fucking head.
