I interpret "out to lunch" as a story about an impulsive man who, alone in this world (no Gina) is quickly distracted by new pursuits (the juggling he's only ever saw before.) Upon failing this pursuit due to his environment, he quickly associates that part of his life to be tainted, and quickly abandons it. Finally free of the perceived toxicity he just rid his life of, he tries again, feeling confident that a new environment will surely fix the issues, only for a new problem to arise instead. He responds to this by shelving his pursuits for a while and abandoning the environment, but this time planning to return.  Am I overthinking a goofy animation?
no
