I have heard similar things, but in my experience, this idea is taken as axiomatic, and then used to prove some other point. I'm looking for a source for this axiom.

Beyond the lack of references, I have a specific question on this. They<br>
seem to be saying that one may deliberately ignore chometz gamur, and<br>
deliberately *not* get rid of it, provided it is smaller than a kezayis<br>
*and* he is not worried that someone might eat it.<br>

Meiheicha teisa? Have we ever been taught such a thing? We are allowed<br>
to keep a small amount of chometz over Pesach?<br>

Crumbs smaller than a kezayis are automatically batel, except "a nice rolls", which one would want to keep if one knew about it (e.g. a wrapped candy).<br>
<br>
There are two reasons why, midrabanan, bitul doesn't help: Lest one find a "nice roll", and lest one find chametz and absentmindedly eat it. These are obviously related; a dirty crumb that one would never think of eating is by definition not a "nice roll" that one would exclude from ones bitul.<span class="HOEnZb"><font color="#888888"><br>
