Santa decided coal was too expensive, so he started putting shredded lettuce and mayo in naughty kid's lockers... he calls it the coal's law.
Santa's New Punishment
Explanation
Explain Bear
Listen up, smartie pants. Santa ain't got no coal because it is too spendy. So Santa uses lettuce and mayonnaise as punishment for being a bad kid. "Coal's Law" sounds like "Cole's Law" which is just a dumb name for shredded cabbage and mayo!
