In our house we have 2 rules:
Dirt IS Chametz and Mommy IS the Korban Pesach.
Thank G-d, "March Madness" is over. We searched our house and found no Chametz! Except for food that some LUCKY GOY somewhere will soon own.
I first met my wife in the zoo 27 years ago the second day Chol Hamoed Pesach. That was our first date. I took her to the monkey cage and assured her that these monkeys are bigger lamdanim than I am [but I know more sports trivia].
