lol It would've been funnier if it was his dad drinking the milk the whole time pretending to be santa
"Pff. You think you can threaten me, Timmy? You think your human poison will do anything to me? I'm eternal, I was here before your star system was formed. My powers trascend time and space, and I do not abide your puny understanding of reality. Yet you thought you could fool me, the Great Klaus? Your hubris will be punished this very night, as you'll never wake up to see your new motorcycle."
You are making a logical fallacy that this godlike creature can be poisoned or blackmailed
Santa knows everything. The moment Timmy does that he will get on the naughty list. Dunno whether Santa eats cookies and drinks the milk, when he is delivering some coal ...
Timmy the next day:
So very Lao Che of you, Timmy...
As if a kid could make a poison to kill this god
Don't be fool santa the antidot is in the cookies
