Jokes would also be topical; for instance, "Over 105 in Los Angeles" (presumably referring to the temperature) instead led to "Under the Reagan plan, how old would you have to be to collect Social Security?" The longest laugh ever recorded was given to "Sis Boom Bah," which was the answer to "Describe the sound made when a sheep explodes" and resulted in both Carson and McMahon breaking character to laugh as well. The segment included several running gags. After Carnac said an answer, McMahon would frequently repeat it in a booming voice – ostensibly as a help to the audience – setting up a sneer, putdown, or some other comic reaction from Carson. Carnac held each envelope to his forehead while "divining" the answer, then tore open the end of the envelope and loudly blew into it before removing the index card with the question. Pretending to psychically concentrate, Carnac periodically asked for "complete silence" from the audience, and McMahon would retort that he often got it. Audience reaction played a major role in the skit. Positive reaction would prompt disbelief from Carnac, stating the ease at which he could make people laugh, such as "This audience would laugh at Dinah Shore backing into a meat thermometer." If a joke (often a very bad pun) generated a negative response, Carnac would give a disapproving look, then cast a comedic "Middle Eastern curse" upon the audience (such as "May your favorite daughter be featured in NFL Films' Sack of the Week", "May a bloated yak change the temperature of your jacuzzi", "May you walk a mile under a diseased camel", "May a demented deer lock horns with your daughter's Kawasaki", "May the fleas of a thousand camels infest the crotch of the person seated next to me, and may his arms be too short to scratch", "May a diseased camel be sick on your prayer rug", or "May your proctologist be a frustrated concert trombonist"). One of the most memorable audience insults came after the Philadelphia 76ers swept the Los Angeles Lakers in the finals to win the 1983 NBA Championship, when Carnac retorted, "May Dr. J slam dunk your cat." McMahon's closing announcement "I hold in my hand the last envelope" was always met with a loud cheer, prompting one final "curse". The curse concept was created by "Tonight Show" head writer and Woody Allen collaborator Marshall Brickman. He dubbed
