One of the stars of the Howard Stern show became a human finger puppet today -- when Benjy Bronk got a live prostate exam on-the-air ... courtesy of special guest proctologist Perez Hilton.
As we previously reported, Benjy agreed to the "exam" as part of a weight-loss challenge he made with Howard -- Benjy had to lose 37 pounds ... or else his ass becomes a finger warmer.
Benjy ... knowing it was a lost cause ... threw in the towel this morning -- and accepted the consequences of his bet during a live bit with Perez.
The two traveled to a nearby hotel to carry out the deed ... with Benjy screaming his lungs out the entire time.
In related news, Benjy would not do well in prison.
