Martini Saturday can be observed by anyone, of any religion. Falling between the Christian holidays of Good Friday and Easter Sunday (I think those are things), this tenets of this 19-years-and-running holiday are good friends, tasty drinks, and the #1 comedy of all time - Caddyshack.
To properly observe Martini Saturday, you should:
1. Drink Martinis. Your choice. Even the stupid ones.
2. Watch Caddyshack. This is a good time to refresh yourself on the outtakes/extras segment that came out in the 90s.
That's it. Get ready, and I hope to talk to you on this most glorious of holidays, when I'm egg-smashin' drunk*.
*it's that thing, where you get so drunk you voluntarily smash an egg over your head to see what will happen
