I like to tell a good joke but often forget the punch line.
What is a punchline?
The punchline is the part of the joke that makes you realize its a joke and often contains a second meaning.
What kind of jokes do you like to tell?
I prefer a joke that is not corny but actually funny. All jokes are humor but not all are funny.
Can you tell me why some people don't find ethnic jokes funny?
Joke
A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh and is not meant to be taken seriously. It takes the form of a story, usually with dialogue, and ends in a punch line. It is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning. This can be done using a pun or other word play such as irony, a logical incompatibility, nonsense, or other means
Another kind of meta-humor makes fun of poor jokes by replacing a familiar punchline with a serious or nonsensical alternative. Such jokes expose the fundamental criterion for joke definition, "funniness", via its deletion. Comedians such as George Carlin and Mitch Hedberg used metahumor of this sort extensively in their routines.
Hedberg would often follow up a joke with an admission that it was poorly told, or insist to the audience that "that joke was funnier than you acted." Johnny Carson in his "Tonight Show"
