Nephi and Laman Tags

Ever since we started reading the Book of Mormon with the kids everyday, they have gotten to know Nephi, Laman and lemuel more. One time, when Caleb and Ethan didn't want to do their chores, I jokingly told them: " Fine, I'll call you Laman and Lemuel then". They reacted violently! A bright Idea came to my mind... I made these Nephi and Laman/Lemuel tags. You get the point. If they are good and obedient like Nephi, they get "nephi tags", if they are disobedient and whiney, they get Laman/Lemuel tags. Anybody who earns 10 Nephi tags gets to have a special date with mommmy or daddy ( their choice). But if anybody earns 5 Laman tags, they loose all their Nephi tags and scubs the toilet as a consequence. So far, Caleb is has earned a date with daddy already. The other two each lost their nephi tags and took turns Scrubbing the bathrooms.
