A one-liner is a joke that is delivered in a single line. Many comedians and actors have adopted this comedic method in their act. Some, including Rodney Dangerfield, Bruce Campbell, Steven Wright, Emo Philips, Henny Youngman, Mitch Hedberg, Dan Mintz, Zach Galifianakis, Demetri Martin, Jimmy Carr and Milton Jones have used one-liners to make up a significant portion of their repertoire.
