A little boy got on the bus, sat next to a man reading a book, and noticed 
he had his collar on backwards. The little boy asked why he wore his collar 
backwards.
The man, who was a priest, said, 'I am a Father.'
The little boy replied, 'My Daddy doesn't wear his collar like that.'
The priest looked up from his book and answered, ''I am the Father of many.'
The boy said, ''My Dad has 4 boys, 4 girls and two grandchildren and he 
doesn't wear his collar that way!'
The priest, getting impatient, said 'I am the Father of hundreds', and went 
back to reading his book.
The little boy sat quietly thinking for a while, then leaned over and said, 
'Maybe you should wear a condom and put your pants on backwards instead of 
your collar.'
