Moshe goes to see his rabbi. “Rabbi, last week I missed saying grace after meals.”
“Why,” asked the rabbi.
“Because I forgot to wash my hands before the meal.”
“That’s twice you’ve broken the law but you still haven’t told why.”
“The food wasn’t kosher.”
“You ate non-kosher food?” asked the rabbi.
“It wasn’t a Jewish restaurant.”
“That makes it even worse,” said the now angry rabbi. “Couldn’t you have eaten in a kosher one?”
“What, on Yom Kippur?”
