The word “glasses” can mean “eyeglasses” or “wine glasses.” A popular joke has a comedian state that his mother (or grandmother) “still doesn’t need glasses. She drinks right out of the bottle!”
  ‘
A form of the joke has been cited in print since at leas 1949. American singer, actor and comedian Dean Martin (1917-1995) told the joke in 1963. Since at least 1986, the joke has been associated with comedian Henny Youngman (1906-1998), who was called the “king of the one-liners.”
 
New York-born comedian Joe E. Lewis (1902-1971) told the joke about his own drinking—not about his mother or his grandmother. “I don’t need glasses. I drink right out of the bottle,” Lewis was credited with in 1964.

AND MAKE A SPECTACLE
Cousin Ceedie bought himself some new glasses on his last trip to the city. For his birthday last week he invited his friend, Hawkeye Jones, over to try them out.
 
“But I don’t need glasses,” objected Hawkeye.
 
“Well come on over anyhow,” insisted Ceedie. “I’ll let you drink out of the bottle.”—Chicago Tribune.
