This is quite simple, I'm going to post a riddle, and once the correct answer is given, I shall post another.
After a while I may allow you to post riddles of your own (When I run out of idea's)
And, bear in mind, the answer, is not always as obvious as you may think.
So, without further ado.
What starts with a C, ends with T, has U and N in the word, is naturally hairy on the outside, and smooth and milky on the inside.
