Although born to a good Irish-Catholic family, Colm had always wanted   
to be Jewish. As a senior in college, he decided to take the plunge   
and go through the formal conversion process. He studied Judaism all   
semester. Finally, he felt he was ready to take the test and complete   
the conversion.   

On the appointed day, he arrived at the Rabbi's office, ready to begin.   

The Rabbi said, "I'm sorry, but before I give you the test we must   
discuss my fee. It's $5000."   

"Holy Moses! $5,000!" exclaimed Colm , "That's a lot of money. How   
about $50?"   

"Congratulations, you pass." said the Rabbi.
