Julius and Irving, two very religious Jewish men, visited Marcus  Pinkus  the
tailor to have new black suits made.

When
they went to pick up  the  suits, Julius looked at his suit very carefully; held
it up to the  light,  walked over to the window and examined it more carefully
and then  proclaimed, "Marcus, this suit is navy blue. It's not black!"

"Trust me." said Marcus, "It's black!"

"Irving, what do you think? Blue, or black?" asked Julius.

"To
tell you the truth," said
Irving, "I couldn't really tell from this light if it's
blue or black"

They
left wearing their new suits and while walking down the street kept examining
each other's suit to see if it was blue or black.

Then
they spotted two nuns standing on the corner and decided to go stand next to
them.

They
knew their habits would be black and this way they could be sure.

Well, later that afternoon, the two nuns returned to the convent and visited
with mother superior to discuss their day in the city.

"A
very strange thing occurred." reported one of the nuns.

"Two
Jewish men approached us on the street and they were speaking Latin!"

"Latin?" exclaimed mother superior. "Jewish men don't speak Latin; they speak
Hebrew!"

"No." said the other nun. "It was definitely Latin!"

"Well, what did they say exactly," asked the mother superior.

"I'm
not really sure," said one of the nuns. "They just kept repeating the same Latin
phrase, "Marcus Pinkus Fuctus!"
