Depends on what you mean by naughty probably. Naughty as in, does he make mistakes or not take care of himself sometimes... yes, I'm sure. Naughty as in cruel or offensive... no. Santa is good.
Well, I think that everyone makes mistakes sometimes, including Santa. He sometimes mixes up the gifts and he forgot Mrs. Claus' birthday once. (Wow, that was a bad year.) But usually he is very, very good and tries to help everyone as much as he can.
Santa often has a childlike outlook on life, and that means he sometimes gets up to some mischief. He enjoys pulling friendly pranks on the elves, and sometimes he slips extra cookies out of the kitchen. Overall though, he never does anything that might get him taken off of the nice list. (Except that one year with my birthday.)
Well not necacerintly there is a good Santa Claus but... santa Claus does have a naughty and good list if that's what you ment?
One can find a Santa Claus Naughty or Nice list on a website called Claus. There is also a website called Email Santa which offers something very similar.
Lumps of Coal
Santa Claus doesn't usually dance, but sometimes Mrs. Claus talks him into it.

checking the naughty and nice list three times
Traditionally, a lump of coal is left by Santa Claus for children who have not been good.
Good children get gifts and naughty one a chunk of coal.
Of course he does, silly! That's how he learns if we're naughty or nice!
The legend says that Santa Claus has a book that keeps track of the naughty and nice children. Santa Claus keeps track of every children's attitude and personality. With that being said, "Just be good, for goodness sake's".
So that Santa Claus knows what they want for Christmas.
If he does, he is one weird dude, but I don't think he does.
