There are players that try to imitate others, but at free-kick time it is a personal thing. Every person has their own technique and routine when they stand over the ball and I have mine, I am not trying to copy anyone.
An aspiring comedian must be determined to get to his or her true feelings on a subject and convey that to the audience. Figure out what you're feeling or interested in because the goal is to get the audience interested in what you're interested in. Good stand up comedy is drawing people into your head.
