Searching for a Barks story

[D.M. van Eijmeren]

First, I wish everyone a happy 2009!

By e-mail, I got the following question, in reference to a Barks story in 
WDC 92:

But I was wondering, did Professor Clabberhead ever say,'You are suffering 
from a slight touch of momentary fragmentation, plus a compound transaction 
of the pandemonium, in addition, a compound bucolic semi- lunar confiscation 
of the basic rathbone' ?' in that comic? my sister loves to quote that, and 
seems to think Clabberhead said it, but I couldn't find it in that comic. 
Was there another version?

Can someone identify this story?
I checked doctor U. Qwik in 'The Mad Chemist' (WDC 44), but I didn't see a 
match.

Best,
Daniël
