Dear Waiting in Anticipation,  yes, but you can't call him Dwindy the Dwarf. (Please see copyright page)

Dr Dwindy, is it true that the weather is always nice on Nod?
                 Keenly Interested

Dear  Keenly, no it is not true, as it is quite often subject to violent changes in weather due to experiments with other dwarfs.

Dr Dwindy, is it true I can ask you anything?
                 Interested

Dear Interested, No, you can not ask that! or that! or that!!!

Dr Dwindy, why is a peeping Tom called a peeping Tom, and not a peeping Sally or William?
                 Tom

Dear Tom, because they are!!!
 

Dr Dwindy, how are we supposed to believe that Nod exists with no proof or contact?
                 Skeptical

Dear Skeptical, what do you call me then? And if you're in that much need to see Nod, watch Star Wars. Near the start, as they enter hyper space, it flashes past on the left.

Dr Dwindy, why do cows mooo?
                Terribly Confused
 

Dear Terribly Confussed, they dont as they are not cows but rather extremely large beetles that when they get excited they like to move around but when they tell the other extremely large beetles to move they forget that they can not pronounce "ve" in move so it comes out MOOOOOOOOOOO. They do also say many other things like, "geranium" and "protagonist" but no one person ever spends enough time with them. Perhaps this is something you should look at doing...?
 

Dr Dwindy, why are my friends soo strange?
              One of Jeff and Nigel's friends

Dear One of Jeff and Nigel's friends, dont ask me, you chose them!!!
 

Dr Dwindy,
All my friends keep calling me "the worm that you are."  What should I do? BONG!
               love lolly girl

Dear lolly girl, kill them, so that they become fossilised... like the worms that THEY are.
 

Dr Dwindy, 
You give such good advice - who should I start with? (the killing, I mean so that my friends fossilise like the worms that they are) The queen, perhaps, or
Sven, or the monkeys, or the fish.  Oh, I have no fish.  Help me,
             love Lolly Girl.

Dear Lolly Girl,
If you have no fish, then go queen!
 

Dr Dwindy,
I was just wondering how do you make a whale?
            banker 

Dear Banker, 
One HELL of a big stork!!!
 

Dr Dwindy,
You look remarkably young for a 200 year old whats your secret?
          avon calling

Dear Avon Calling, Immortality has it's advantages. Plus, I use Oil Olay twice a day.
 

Dear Dr. Dwindy, what is the best pick-up line on Nod?
          D&D (desperate and dateless)

Dear D&D, here are some common pickup lines used on Nod:
      Fairy : Nice wand!
      Dwarf : This is a hold up! Now hold me up!
      Dragon : Come and light my fire!
