This reminds me of "Invisible Boy" in the movie "Mystery Men":
Shoveler: So, let me get this straight. You do have the ability to become invisible? Invisible Boy: Yes. Shoveler: But you can't give us a demonstration? Invisible Boy: No. I can only become invisible when noone's watching. Shoveler: So, you're only invisible to yourself? Invisible Boy: Oh, no. If I look at myself, I become visible again. Furious: So...you can only become invisible when absolutely nobody is watching you? Invisible Boy: Yes. Raja: Um, do forgive our incredulity, but um...I'm wondering how you can be certain you've acheived transparency at all? Invisible Boy: Well, when you go invisible...you can feel it. Furious: Okay, I'm leaving.
