"I've actually become much, much dumber through being married and having these children. I find that I'm not half as sharp that I once was. I can't even help them with their 4th and 5th grade vocabulary and math work at this point"

This quote by Patrick Warburton speaks to the concept that marriage and having children can be a major life modification that can have a substantial impact on one's mental capacity. Warburton is recommending that he has actually become "much, much dumber" considering that getting married and having kids. He is indicating that he is not as sharp as he when was and is unable to help his children with their 4th and 5th grade vocabulary and mathematics work. This could be due to the truth that he is now juggling several duties and is not able to commit as much time to his own mental development. It could likewise be because of the truth that he is now in a various stage of life and his priorities have shifted from his own psychological development to the advancement of his children. Whatever the reason, Warburton is recommending that marital relationship and having actually kids has had an unfavorable impact on his mental capability.
