Today's Daf-Yomi treasure (Shabbat 12)

One shouldn't kill lice on Shabbat; one who kills a louse is as if he killed...a camel.
Small, black, scuttly, sucks blood; big, yellow, clompy, spits. Got it. Next time I find a camel in my clothes, I'll know that if it's a weekday, I can squish it between my fingernails.

You can't use a lamp (lest you come to make it burn brighter, which is bad news) to work out which are your clothes and which are your wife's clothes. Aren't men's and women's clothes usually fairly different? Rashi says only workers' clothes - city slickers don't do any work, so they wear wide garments like women.

I thought that was cute.
