Andy Daly is absolutely one of the funniest character/improv comedians out there right now, and an Upright Citizens Brigade theater alum. Kinda surprised baleen hasn't come across him before. I have been listening to his CBB appearances recently and they are amazing.
Andy Daly on Comedy Bang Bang is almost always amazing. His Limerick writer is one of the funniest things I've ever heard. And then there was another episode where at the end all his characters for basically no reason all come in to commit suicide, it's astounding.
