I already provided proof, but you didn't take them into account. The links I listed above are from websites prepared by Alevi/Bektashi organizations who intend to provide reliable information on their culture and beliefs. They also include articles by international researchers. If you cared to check them, you'd see they all assign an important place to Bektashi humor & wit, and provide examples. If you need additional proof, please search for "Bektashi", "Bektasi", "Bektashi jokes", "Bektashi humor", and you'll get plenty of answers for your question. I wasn't able to understand the relevance of your first sentence.
