I must say, though, the horror that Andy could potentially unleash as a guest is as nothing to the idea of Andy...as a host.
Well, that's terrifying. Though, cheerful thoughts (speaking as someone who has also stayed as a guest in an AirBnB), hosting with any level of success would require:

• Keeping his living space immaculately clean, beyond even "comfortably cluttered" levels of clean, which he can't;


• Anticipating the needs of others (stocking up on fresh coffee before it's asked for, say), which he can't;


• Knowing when to give people their privacy, which he can't, due to his need for constant attention;


• Being able to advertise in a non-hyperbolic way, because stuff like "we serve a four-course gourmet meal every night" is going to get you visibly bad reviews if you can't deliver.

Even if Andy had the space for an AirBnB setup, he'd get bad reviews fairly quickly because it requires understanding and fulfilling the needs of other people, and he can't think of anyone other than himself.
