An Experiment

I've never done this before but I thought I would try it as an experiment.

I am trying to come up with a topic for this week's shiur and I can't find anything that I haven't spoken about and grabs my attention.
Therefore, I am asking all my readers (which probably amounts to 1 or 2 people) for suggestions. The only requirement is that it has to somehow tie into the parsha and it should be halacha or lomdus oriented.

I can't promise that I will use any of the suggestions but I will definately consider any suggestion that I get.

Thank you in advance.
