"Yikes" is a reaction that George Michael exclaims twice. In both instances, it was in response to a Fünke.
Tobias: Oh, give me the suit. Give me the suit.
George Michael: I’m actually wearing it right now, but I can’t tell you why.
Tobias: You’re wearing it right now?
George Michael: I have to wear it all the time. You... you’d never understand.
Tobias: Oh, please, I’ll never un...? I’ll never understand? That you can never be nude? I understand more than you’ll... never know.
George Michael: Yikes.From "In God We Trust"
Lindsay: There’s nothing wrong with that. Although... I must say I’m a little hurt that you haven’t considered me.
George Michael: You’re my aunt.
Lindsay: That doesn’t matter. Aunts can fill that role. Teachers can fill that role. And, someday, you’re going to find the right woman to fill that role. But until then... I’ll be right across the hall.
Narrator: Lindsay had never been more proud of anything she had said in her entire life.
