In one of Mikhail Ancharov’s books there is such an example. Imagine that you are at the idea of Hamlet. And just Hamlet starts his "be or not to be", when suddenly his pants begin to subside. He is about "what is noble in spirit," and the pants fall, and he holds them, and they fall, and that's it. And although this is a tragedy, you are disassembled by uncontrollable laughter, from which it can be disgusting, but still funny.
