Hardly Boys

The Hardly Boys a paradies of the Hardy Boy characters. They appear in the South Park episode "Mystery of the Urinal Deuce".

History
When Mr. Mackey becomes obsessed with discovering who crapped in the boy's room urinal of South Park Elementary, he contacts the police, who in turn hire the Hardly Boys to help figure out who was responsible. Upon being summoned, a voice-over gives them a form introduction of "two young whippersnappers with a knack for solving mysteries". However, upon arriving at the scene, they both prove to be apparently inept, by constantly saying that they are feeling "raging clues" which in truth means they are both getting erections. They both seem to talk with their teeth firmly closed shut and with homosexual lisps, and spend most of their investigation moaning about their "clues". Whenever they around both they and those around them continuously make innuendos to erections.

They are later also hired to solve the 9/11 conspiracy, in which Cartman has been claiming the Jews (Kyle in particular) is responsible. Once again, the boys appear to be solely concerned with their erections, rather than the investigation of the case. Later however, when Stan and Kyle meet the Hardly Boys' detective father, Mr. Hardly informs them that the Hardly Boys managed to discover the truth behind both the Urinal Deuce and the 9/11 Conspiracy, by "following their clues." After the case is solved, the Hardly Boys set out to follow more "clues".

Oddly enough, despite being real citizens of South Park, the Hardly Boys also have a book series that is shown during their introduction montage. The books are written by Fredrick Dickinson. =Titles of the Hardly Boy Mysteries=
