Born in Popekeke Hawaii after a diaper fell from Flying Sleigh at the birth of Insanity and his twin, Santa. The sleigh was traveling so fast, the same method used to determine Santa's birthplace indicated Zug Switzerland.
Insanity Claus was technically born first, but since Santa was born on the other side of the International dateline, on records, Santa is listed as being born first.
Insanity Claus lives at the South Pole and is very jealous of his famous brother, Insanity enters your home via the toilet, to leave shitty gifts in the bathroom
