A company takes out a newspaper advertisement claiming to be able to 
supply imported hard core pornographic videos. As their prices seem 
reasonable, people place orders and make payments via check.

After several weeks, the company writes back explaining that under the 
present law they are unable to supply the materials and do not wish to be 
prosecuted. So they return their customers' money in the form of a company 
check.

However, due to the name of the company, few people ever bother to present 
these to their banks. The name of the company: 'The Anal Sex and Fetish 
Perversion Company.'
