Because he is signing like a bird released.

That's a deaf bird who can't sing
Jesus Christ, anon!
You think that deportation didn't have ulterior motives?
How often do he and his supporters get called nazis?
I am not so certain it was cannabis he was smoking (badly).
Wasn't being technical, anon, I was suggesting that it was no more than a stunt and no cannabis was involved in the making of that show.
That's the part I have yet to figure out, but it seems just too bizarre!
