Tex Avery fills maybe a quarter of “Sh-h-h-h-h-h” with sign gags. The premise is the hotel where Mr. Twiddle is staying at is supposed to be quiet, so the communications are in silent signs. I like how the bellboy flips around one sign and it has three messages. No need to ask why it doesn’t have two (one on either side); it’s a Tex Avery cartoon.
Being a silent cartoon during this portion, the drawings say it all.
Ray Abrams, La Verne Harding and Don Patterson animate this, Avery’s last completed theatrical cartoon.
