Doonesbury by Garry Trudeau for August 20, 1977
Duke: In conclusion, a word of caution to all those youngsters who look to me as a role model... stay off the hard stuff! Unless you know what you're doing, it can only come to grief! There is no room in the drug culture for amateurs! Thank you! Voices: Baa! Baa! Baaa! Baa! Duke: Bad craziness... Man: Bleat! That was just bleat!
