There is no definitive answer to what the funniest joke in the world is, as humor is subjective and varies from person to person. However, there have been several attempts to identify the funniest joke through research and surveys. For example, Richard Wiseman of the University of Hertfordshire conducted an experiment called LaughLab in 2002, where people could rate and submit jokes from different cultures and countries. The winning joke, which was later found to be based on a 1951 Goon Show sketch by Spike Milligan, was submitted by Gurpal Gosal of Manchester: "Two hunters are out in the woods when one of them collapses. He doesnt seem to be breathing and his eyes are glazed. The other guy whips out his phone and calls the emergency services. He gasps, My friend is dead! What can I do? The operator says, Calm down. I can help. First, lets make sure hes dead. There is a silence; then a gun shot is heard. Back on the phone, the guy says, OK, now what?".

Other sources, such as Readers Digest and Humor That Works, have compiled lists of the funniest jokes of all time based on surveys and research. However, its important to note that what one person finds funny may not be funny to someone else. Ultimately, humor is subjective and what one person finds hilarious, another may not find amusing at all.
