"A lot of times when I sit down with the other comics and try to talk theory, they say I'm being too serious"

This quote by Joel Hodgson suggests that he takes funny seriously and has an interest in going over the theory behind it. He is suggesting that other comics don't take comedy as seriously as he does and do not wish to talk about the theory behind it. This might be because they don't understand the theory or do not think it's crucial. It could likewise be due to the fact that they don't want to put in the effort to think critically about comedy. Whatever the reason, Joel Hodgson is clearly passionate about funny and wants to have significant conversations about it with his peers. He is disappointed that they do not share his enthusiasm and do not want to engage in the very same level of discourse.
