Die Beziehung des Witzes zum Traum:
A Scotsman, a priest, and a rabbi,
walk into a bar.
(and somehow, in some sense, I am that rabbi -- so clothed on the instant, like Woody Allen in that Thanksgiving scene)
Only now, the priest is (at the same time) a polar bear.
The bartender, clearly concerned, leans forward and murmurs:
“Why the long face?”
[χορός : What happened to the Scotsman?
Dreamer: I -- oh. Was there a Scotsman?]
