My review from the NHC:
I'm surprised it took this long for them to make an MC Hawking joke, who is a real rapper who sounds like the robotic Stephen Hawking. And the final song sounds almost like a parody of "Promiscuous Girl" by Nelly Furtado.
As for the episode, Homer and Bart's side of story was "F Grade" filler and it shouldn't have even been in the episode. Lisa's side didn't help, either. The whoopty-do Glee crap was over quickly, but I wished Lisa could've visited the kids in the city instead of the councilors and the Glee Kids were all crack addicts, or something
Also....STOP WITH THE PUNS, AL! THESE STUPID ATTEMPTED PUNS ARE NOT FUNNY!
Anyway, I'd give this a healthy 2/5.
