Secret Masonic handshakes

The Freemasons are renowned for getting a number of hands signals by way of which their people can identify one another wherever they could happen to be on the planet. Now you can also pretend to become a Freemason. The secret's that, first, you have to commit to memory a number of hands signals which indicate different days each week. The signals also require you have pockets inside your clothes (or you have clothes on, period... so these will not operate in a nudist colony):

Sunday sign: right submit pocket of breeches, with thumb out, pointing left side.
Monday sign: left submit left pocket, thumb out, pointing right side.
Tuesday sign: right submit right waistcoat pocket, with thumb out, pointing left.
Wednesday sign: the reverse—left submit left waistcoat pocket, with thumb out, pointing right.
Thursday sign: right submit right coat pocket, with thumb and forefinger out, pointing downwards.
Friday sign: exactly opposite—for right, read left.
Saturday sign: putting the very first three fingers from the right hands to that particular area of the right eyebrow then the ear, and thus drawing it along up until the 3rd finger touches the nose.

Observe that you should be putting on a waistcoat! Let's focus on the key greeting. Whenever a Brother meets a Brother he first needs to give signs of the 2 preceding days, and so the other Brother returns the seventh or Saturday sign. And that is it!

Regrettably, these signs most likely will not work today. The data originates from Strategies of the Freemasons Revealed with a Disgusted Brother, released in 1759. Based on Wikipedia, the Freemasons periodically change their secret signals, to be able to have them secret. Nowadays, you may even be needed to create some type of certificate, or documents, to demonstrate your Freemason membership.
