 The rapping male nanny featured on the 2005 San Francisco auditions  was actually comedian Chris Wylde (qv) in disguise. Wylde adopted  a nerdy persona as a nanny, donned clunky black glasses and  auditioned under his real name, Christopher Noll. Instead of  singing, he performed a humorous original rap about judges Randy  Jackson, Paula Abdul, Simon Cowell and guest judge, Brandy. Abdul  and Brandy praised his performance, which was panned by Cowell.  After getting rejected, Wylde spewed out a mouthful of obscenities.  According to the New York Post, Idol producers were unaware the  audition was a stunt.
