How can you not love him?!!

It's B16!






Nope, that's not a Santa hat! It's a 'Camauro'.

"The camauro is the white fur-trimmed red bonnet reserved to Popes in place of the biretta.

The camauro, like the biretta, evolved from the academic cap of the Middle Ages. Unlike the biretta, however, it did not evolve much. The camauro in its present form was established by the twelfth century.

Pope John XXIII in 1963 was the last Pope to wear one."

from here


I'd be willing to bet that the 'traditional' Santa Claus hat actually evolved from the Camauro!
haha! bet the secular world dont know that!
