Re: joke maybe, but you have a point
"Real men only need; Something that cleans when things get too dirty."
You're not a true man if you recognise the concept of "too dirty". If for whatever reason, the dirt interferes with the functional properties of something, you're allowed to clean it, but in isolation, dirt of itself is no reason to clean. Take a sock, that (for whatever dubious reason) has got rather revolting and gone hard, the reason for cleaning is only to remove the hardness that makes it difficult to put to any particular use.
