Mr. Dangerfield's big break came in 1967 when, at 44 and relatively unknown, he won a spot on "The Ed Sullivan Show." Introducing a stream of lugubrious one-liners with his loser's prologue - "Nothing goes right for me" - he became a favorite guest on shows whose hosts included Steve Allen, Joey Bishop, Joan Rivers, Dean Martin, Johnny Carson and Merv Griffin.
Q : What does "liners" mean in the sentence? I think it refers to an actor with lines about his loser's prologue. Am I right?
All the best,
