Hi Yesman! You are my favorite character on Kappa Mikey! Have you ever thought about no?
Hmm... if the answer to that is yes, you would continue with the title of Yesman however you would not be worthy of this title since you have contemplated no instead of yes.
If you answer no, then of course you could not be a yes man since clearly you cannot answer yes to this simple question.
Let's hope they don't make an episode with that as the basis for your sake.
