Now You're Talking, also known as Tale of the Upright Telephone is an instructional film for the telephone using a combination of animation and live action. This vintage short-film tells the story of a poor desk telephone set. Made in 1927 by the Fleischer brothers, it's a funny animation, but it's more curious than amusing. It's in public domain, available to download at Internet Archive, or to watch at Google Video. There is no sound, it's totally mute.

And now that you learnt how to use the telephone, read a vintage pamphlet with tips of How to Make Friends by Telephone.
