You've seen yourself how the puppets insist on wearing them, and they're so short that they...

[The heat from the blush suffusing his face, combined with the steam buffeting it, already make him feel a bit faint. At least it's almost done.]

I don't believe the puppets need any sort of undergarments, but they wear them as part of it. If I wear that in public, I'll be too embarrassed to do anything.

[He'll just ignore the one time he did wear something like that-- it wasn't really in public if it was just that room, right?]
