I was watching TV at age 9 or 10 and my mom said that I came from the front room and I told her that I want to act. And she said if you want to do this at 18 then you can. It was a very simple story yet I do not even remember the conversation that I had with my mother. Until she reminded me of the story many years later.
In terms of the creative side of it it's really been a thing where you come up with the funny stuff is usually at a bar or out talking to people or whatever.
