growth industry? hilarity strikes again at the daily news...

The Mafia has gotten into a new growth industry: Paying off doctors for Viagra.

The Gambino crime family has been stockpiling Viagra and a pharmacy full of other prescription drugs allegedly supplied by three prominent Westchester doctors, the Daily News has learned.

Drs. Stephen Klass, Arlen Fleisher and George Shapiro have been caught on FBI tapes providing the drugs to gangster Gregory DePalma, according to law enforcement sources.

The agents discovered DePalma then sold the drugs or gave them away to friends and family.

The FBI also discovered evidence that DePalma returned the favor by providing the doctors with stolen goods, including a designer watch, suits and bootleg DVDs.
