I can tell Cajun jokes because my wife IS Cajun, from Chac Bay just outside Thibadaux, Louisiana.
Boudreaux has been going to South Cajun U. just outside of Lafayette, Louisiana, for over 10 years. Everyone loves him because he is so honest, kind, and helpful. His problem is focus. He has been passing lots of courses but changes majors so often that he doesn't have enough credits in any one subject to earn a degree in it. The Dean of Student Affairs finally calls Boudreaux into the office to discuss the matter.
The Dean advises Boudreaux that if he can pass a test, the university will give him a general degree so he can leave. If he fails the test, he has to leave without a degree. Boudreaux reluctantly agrees.
Boudreaux studies in the library for weeks. Near the end of the term, the Dean calls Boudreaux to the athletic stadium. He says, "We are going to give you your test in public so your friends can cheer you on." Boudreaux thinks of the pressure in publicly failing, but what can he do? So he says, "OK."
The crowd starts cheering for their friend, because after 10 years, everybody knows Boudreaux. They all look up to him as a personal inspiration. The noise swells to a great crescendo of "You geaux, Bou-dreaux, you geaux, Bou-dreaux, you geaux, Bou-dreaux."
The Dean signals the crowd of students to be quiet. They settle down. In the sudden silence, he says, "Boudreaux, are you ready for the test?" Boudreaux nods. The Dean says, "Tell me, Boudreaux, how much is 1 + 1?"
Boudreaux looks up to the sky for inspiration, thinks for a long moment, and then says, "2."
The students in the stands start chanting immediately. "Give him another chance, give him another chance."
