First, read How do I create a Poll?. Then suggest your poll here.
Good idea to start a new quest, because the old one was decidedly overgrown, but how 'bout including a direct link to it anyway?
Complete ideas are more likely to be used.
Well, it's not complete due to me not being very expert in this area, but I expect knowledgeable people to give helpful contributions...
Since I misunderstood the last poll myself and others mentioned other famous doctors from various tv series or movies, how about another poll with a title, as a pun, identical to the former one, or perhaps with a lowercase "d", as follows?
The best Doctor:
Update: added Moriarty's suggestions. Incidentally, while searching Wikipedia for his suggested entries, I found a list of fictional doctors, that may be helpful: time permitting I'm browsing it later. Unfortunately, I couldn't find Dr. Kildare there...
Update: added anonymonk's suggestion as long as two other ideas of mine.
Update: added planetscape's suggestion.
Update: added girarde's suggestion.
Update: added ryanc's suggestion.
Update: added Lady_Aleena's and jdporter's suggestions, as well as an option of mine. Also included the link for Dr. Kildare, which funnily enough I couldn't fine, which in turn is very strange since its wp entry is there since September 2nd, 2006!
Update: [Thu Dec 6 21:25:57 2007] added bdimych's suggestion. (Incidentally, thank you for the direct links, but FWIW you can use the Monastery's shortcuts instead of hardcoding a tags, check the source of this very node to see how!)
