What jokes are interesting to tell, but boring to express in words?

My friend is great. I remember in junior high school, my buddy smoked in the toilet during his lunch break. Buddy took the last bite. He jerked and the dean suddenly came in. Seeing us leaning against the window, I asked, "What are you two doing?" I panicked and turned to look at my buddy. I remember his performance! He blew a lot of smoke from his nose and said, "I'm angry." I didn't feel it when I wrote it like this, but it was funny when I said it.
