I just received an e-mail from Professor David Berger which includes the following:
I wonder if I ever told you the best cross-cultural, cross-linguistic one-liner I ever heard.
A yeshiva bochur asked his rebbe if it's muttar to go to the opera. The rebbe replied, "You're not over till the fat lady sings."
To understand this one line, you have to konow about kol isha, you have to know yeshivish, and you have to know the American expression about the fat lady.
I reprint it here, with attribution because, as he writes: 'Ba-avonoseinu, we need things to laugh about.'
