It originally aired in the US on November 16, 2005. It hasn't aired in the UK yet, and I guess it won't.
Notice it doesn't name the "nervous TV bosses" ot even the corporation? I wonder if it's even true or is just hype. I mean... the "What we'll miss ... how Tom might look on show" is preposterous, since the show is done, and they know how he'll look. Yet they've got him dressed as Kyle.
This reminds me of the "Puerto Rico Day Parade" episode of Seinfeld and how NBC wouldn't rerun it because of a scene where Kramer accidentally set a Puerto Rican flag on fire.
But anyway, that was a funny episode of South Park. I like how the credits read 'John Smith'...'Jane Smith' over and over.
