You would love it. It's called The Endowment Ceremony and it's super secret. You even get a new name that is your temple name. You dress in white and wear this cool pleated robe that looks like a toga and this funky hat that has a string you tie to a special loop on the toga. Then you wear an apron like a mason but it's not a masonic apron it's like green fig leaves. Ha! ha! It's totally asinine.
Ok so you get these signs and tokens which are secret hand shakes that mean different things and you have to memorize them to get into the holy of hollies of the temple. There are four secret handshakes and when you are shown them you swear a death oath that you will never divulge them. One penalty is having your tongue ripped out by its roots. The other one your throat is slit. The third one your are disembowled and I forgot the fourth one.
Anyways all this super secret stuff is on the internet and anyone interested now knows so so much for secrecy.
