Rodney Marks is a corporate comedian. He's based in Sydney and performed around the world. His comic hoax routine relates to the Impostor Syndrome. Many people feel unworthy of their senior roles, and are (unjustifiably) fearful of being caught out as frauds. This insecurity is almost never based on a genuine deficit of talent, skills or experience. It's a lack of confidence. When we see a comedy performance by a corporate impostor, we're reminded of the importance of confidence by a confidence trickster in a safe environment and it's great fun. Rodney says his fees are risable! www.comedian.com.au
