Feast of the Tabernacles
Thank God we live in a country where almost everyone has heard of Rosh Hashana and Yom Kippur. But then, Succos comes around and you are taking off two days.
"Boss, I need to take off for a Jewish holiday."
"Really? I thought you just had them."
"Well, there is another one coming up."
"Oh, what is it about?"
"Well, we build these little huts and sit in them waving some palm branches."
At this point, they usually start looking at you funny. I suspect they think I am pulling their leg. Now, when Shmini Atzeres comes around, I don't even try to explain...
Lately, I've been using a strategy that seems to work pretty well. When people ask me about Succos, I just say - "It's an old Biblical holiday - I believe the Christians call it 'The Feast of the Tabernacles'". This usually shuts them up and they leave you alone. No more questions.
I think most people have no freakin' clue of what a 'Tabernacle' is...
