How about feeding animals on Yom Tov and shabbos? Once on pesach we were enjoying a sit in the park, and a young mother comes along with her brood of children and a bag of whatever, matza crumbs? And the start throwing it to the birds for fun.
How about washing netilas yadim and sitting at your place when you put the challa in your mouth, and actually swallowing a kezias or at least a drop before resuming partcipating in talking?
Or in one house the rebbetzin was washing each and every dish that returned to her kitchen after each course, and faithfully replacing them in the cupboard so everything should be in order, after drying with a towel, as well. As well as wiping the counter tops with a shmatta.
