Balloon mortal combat

How to be condesending - Lesson 1:
State the obvious in a very explanatory voice, conveying the impression that this might be something unknown to the other person.

example: "There are three parts: part 1, part 2, and part 3."
Really I thought that the three parts would be part 1, part root 3, and part vodka.

edited to add:
example 2: "We're concerned with anything that has come out since the 1985 publication. So anything from 1986 to the present day."
