Jokes are short funny expressions or stories meant to make people laugh. Wordplay, irony, or some other kind of twist often make them laughable. Jokes may take many forms including simple one-liners or more elaborate set-ups with punchlines at the end. They are social instruments used to ease tension; hence they serve as icebreakers, lighten moods, and create a sense of camaraderie among individuals. A girl must know that for a joke to be effective it must be appropriate for the occasion and well-timed. What is funny may not necessarily be humorous for others because humor has various meanings. Generally speaking, jokes can be regarded as an important way of communicating socially worldwide in order to relieve stressful situations and harmonize human relationships.
