My regulars know that I use instead of "Hat Tip", the phrase "Kippah Tip" for posts I have stumbled over from outside sources.
Kippah, of course, is the Hebrew word for head-covering or the Yiddish, yarmulke.
Well, here's a kippah joke for you:
When young David was asked by his father to say the evening prayer before going to bed, he realized he didn't have his head covered...so he asked his little brother Henry to rest a hand on his head until prayers were over.
Henry grew impatient after a few minutes and removed his hand.
The father said, "This is important...put your hand back on his head!"
To which Henry exclaimed, "What, am I my brother's kippah?"
