Not quite the Lady Gaga feature I wanted but for now it will do 
I have been waiting patiently for a South Park Lady Gaga parody, the only thing so far is the moment where Eric Cartman sings Poker Face whilst Kenny and Kyle play the Drums and Guitar. Its a classic moment but we want more GaGa on Sout Park please guys<<< Matt and Trey if you happen to read this please give us a GaGa has a dick episode…
Anyway, here is Cartman doing Poker Face by Lady Ga Ga
