I seem to have developed an addiction to puns clerical. Won’t anything curate?
The vat, it can.
Euty, I beg your pardon… we never promised you a rose, warden.
Clerical puns are a hard abbott to break. They’ve looked for a cure but there is nun. You’ll just have to pope for abbess. Good luck trying to get your insurance to pay for treatment too. Most consider it a prioress-isting (or priest-existing) condition.
To completely change the subject, if you stare too long at a Klein bottle and get disoriented and nauseous, are you suffering from Mœbic dysentery?
I don’t know what a Klein bottle is, so I can’t prelate to the last pun.
matt, you should really try to contain yourself. 
OTOH, I once saw a very elderly priest try unsuccessfully to dispense holy water from a Klein bottle. The poor old fellow was obviously suffering from senile dimensions. Does that clerify matters for you, Otto?
