Kuhn and the Ashtray Argument

In case anyone out there still doesn't know, the New York Times is publishing a five-part series by film-maker Errol Morris about his days as a grad student at Princeton supervised by Thomas Kuhn.
I must confess I'm having a hard time believing the ashtray anecdote related in Part One (if only because the ashtray-throwing Kuhn reminds me a bit too much of the poker-brandishing Wittgenstein) but at least it makes for an entertaining reading.
