John Mahoney said this quote

“ I didn't want to be the archetypal sponging brother-in-law, so I didn't go into acting when I got to the States. I thought, 'No, I'll go to school and then I'll be an English teacher; that'll be fun.' But I was horrible as a teacher. As hard as I tried, I just couldn't inspire those kids to take an interest in Milton and Shakespeare and Donne. ”
