I know this isn't the main point of your post but everyone has already addressed the bigger issue (I agree: no more talking to friend about T) so I wanted to comment on the comedy routine aspect.

Comedy is like any other piece of writing you might share with your T. Most comedy is full of big and painful issues. It's often pretty personal stuff and there are some pretty raw truths in there. There's a reason that so many great comedians come from groups that have faced considerable oppression and/or have experienced a lot of personal adversity. Think about the jokes people make about their weight, ethnicity, social class or marital problems to name a few. I think that shyt is a freaking therapy goldmine!

T critiquing your comedy routine can involve helping you get to the heart of the issue. Sure you make light of it with your audience. But you can actually cry about it with your T.
