One-line joke
A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy. Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright, Henny Youngman, etc. Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes short and witty quips after disposing of a villain.
Examples
One Line
Do you remember the first kiss?
Star shooting across the sky
To come to such a place as this
You never left my mind
I'm watching from the wall
As, in the streets, we fight
This world all gone to war
All I need is you tonight
And I draw a line
To your heart today
To your heart from mine
A line to keep us safe
All through the rising sun
All through the circling years
You were the only one
Who could have brought me here
And I draw a line
To your heart today
To your heart from mine
One line to keep us safe
And I draw a line
To your heart today
To your heart from mine
And pray to keep us safe
Watch the stars now moving
'Cross the sky
Keep this feeling
Safe tonight
