I must say I find television very educational. The minute somebody turns it on, I go into the library and read a good book.

Groucho Marx (1890-1977) American comedian [b. Julius Henry Marx]

“King Leer,” Tele-Views (Sep 1950)

Commonly paraphrased: "I find television very educational. Every time someone switches it on, I go into another room and read a good book." A number of uses of this line by Marx are found around the same time frame, with variant wordings. See here for more discussion.
