Have you tried gluten free ginkgo biloba bee pollen salt lamps? Sorry, I had to. But here's an actual real suggestion that may or may not be any better.

In addition to what other people are saying re: comedians and practicing, I've also found regularly doing a few rounds of Dual N-Back (or anything else that has me juggle multiple memories while working with logic, like leetcode or logic puzzles) almost magically bumps me up a tier on the banter-o-meter too.
