Missing Gene

There must be a cleaning gene that's missing in my DNA. I'm perfectly content to just let dust and papers cover the furniture and dishes pile up in the sink . . . until expecting company.  Then I feel compelled to straighten up the mess, dust, and vacuum.  This trait can't possibly be laziness because I'm always busy doing other more important things such as email, Facebook, tweeting, or reading, etc.  No, it has to be that missing gene.

I just wish scientists would hurry up and announce the existence of the cleaning gene (or absence thereof) so I'd have some validation.
