"I don't know why I had this thought, but I will just say it.

What if Santa's sack is just his ballsacks, and when he unleashes his load the sperm forms into toys, when he first starts, he is all pent up for waiting a whole year to wank it. The first children house he visits gets all the good ♥♥♥♥, because he is loaded, and when he nuts the sperm turn into toys. As the night gets longer, he gets more dry which results into crappier toys. Eventually when he runs out of sperm from being all empty, he just ♥♥♥♥♥ in a bag and gives it to children calling it coal." -Pie
