"I'll probably make loads of plans, and then just sit around on my bottom all day long and do nothing"

John Deacon's quote is a funny method of expressing the typical human propensity to make strategies and then not follow through with them. He is suggesting that he will make a great deal of strategies, however then not really do anything. This is a common issue for many people, as they typically make plans however then get sidetracked or overwhelmed by other jobs. It is a funny way of expressing the idea that we often make strategies however then don't follow through with them. It is also a suggestion to take action and follow through with our strategies, instead of simply making them and after that refraining from doing anything. By making this joke, John Deacon is encouraging us to take action and follow through with our strategies, rather than just making them and after that refraining from doing anything.
