I'll start off by noting that I understand that a rookie who has been decent but nothing spectacular does not really deserve a nickname. I'm not starting this up because he really needs one or anything.
Here's the story. My younger brother is a big NBA fan but not a college hoops fan at all (that's what happens when you go to a school based on academics and not sports - I went to IU). A couple years ago we were watching the tournament and saw Hibbert play a bit. My brother thought it was hilarious because all he could think of was Dr. Hibbert from the Simpsons. Every time Roy made a play, my brother would do the Dr. Hibbert chuckle.
Now that the Pacers have him, when we talk about Roy, we refer to him as Dr. Hibbert. A week or two ago, my brother asked me if that was his nickname and I told him that unfortunately, we're the only ones that call him that. So the question is, does that nickname work? Do enough people care about the Simpsons to find that funny? If I start referring to Dr. Hibbert, will I be laughed at?
Just a thought
