nedarim 81

rabbis' sons are notorious for treating the torah and the community like dirt.

and dirty clothes can drive one to madness.

this page asks a great question, often asked in jewish communities. why are rabbis' sons such jerks? (actually, the question is why Torah scholars are born to paupers and not to Torah scholars) the answer is that rabbis' sons are arrogant, and take advantage of their father's status in the community and don't respect the Torah. Also on this page is the discussion about the importance of laundry, because dirty clothes can cause madness. 

shabbat 62

beauty, jewellery and perfume

becomes haughty
and makes a stench that cannot be masked by herbs.

(discussion on the types of ornaments and perfume that women can and can't wear in public as they are considered carrying, leads to a description of the decedent behaviour of the northern kingdom and the first temple period that led to exile and was punished by marking and disfiguring the body. for english translation of this talmud page, see here)
