Remember who he's voice by. I believe he's excused from the fourth wall entirely.

MFW not wearing gloves.

I actually know the answer to this one.

Since the classic Disney characters had fully black bodies (with te exception of Donald and Daisy Duck) when they would do something that required their hands to be behind/infront of them, people could not tell what on earth they were doing so the white gloves just became a way to see their hands better.

They could put their hands down their pants and we wouldn't know what they were ''doing''
