perhaps LW should just stash some random matzo around their yard and wait for the baffled complaints.

While I like the snarkiness of that idea, matzah would turn to mush pretty quickly if it's out too long. There are plastic eggs that one can buy, and put matzah into... but that goes back to the "don't have time for it" aspect. (And, maybe it's just me, but I always worry I don't have enough matzah before Passover. That's probably why I bought way too much this year. After Passover's over, well... this video is a cute video which gives an idea of what my feelings might be.)
