Fascinating - that's very similar. The speech was a one-off, long ago so perhaps my memory is distorted and that Tumblr is closer to the original. I don't know if I ever knew who the student Rabbis studied with originally. They'd show up unannounced, stay for a few weeks or a couple months, then be gone. I imagine the parents knew more about it, but nobody told the kids.

Except the one...

One of them showed up with a bumper sticker on his car that said "Shiksas are for practice." He... didn't last.
