but this story was around CU in the late Seventies...
-----------------------------------------------------------------------
It seems that during an examination one day a bright young student popped up
and asked the proctor to bring him Cakes and Ale. The following dialog
ensued: Proctor: I beg your pardon?
Student: Sir, I request that you bring me Cakes and Ale.
Proctor: Sorry, no.
Student: Sir, I really must insist. I request and require that you bring me
Cakes and Ale.
At this point, the student produced a copy of the four hundred year old Laws
of Cambridge, written in Latin and still nominally in effect, and pointed to
the section which read (rough translation from the Latin):
"Gentlemen sitting examinations may request and require Cakes and Ale".
Pepsi and hamburgers were judged the modern equivalent, and the student sat
there, writing his examination and happily slurping away.
Three weeks later the student was fined five pounds for not wearing a sword
to the examination.
