To drink or applied externally?

However you like, either way it'll give you an instant chill.

Depends on how you are exposed
If you keep a layer of gas between you and the liquid nitrogen (i.e. only small amounts, don't contain it) then its just cold since the gas insulates you.
Just splashing it on the floor is also nice and cooling (and fun)

Yes.
I was being facetious.
