The Best Old Simpsons Short from 2006

My Opinion on The Movie centers Around Principal Skinner
doing a 15 mins Test, but the funny part
is where when Bart and Millhouse sing Jingle Bells
from The 1989 Christmas Special (aka The Very First Episode of The Simpsons)
then Nelson Muntz says "Ha-Ha", Then 15 mins Later,
it ends with Principal Skinner saying that is time to end the test,
and the movie ends,
the movie was great, it reminds of That Terrance and Phillp song
from The 1999 film: South Park: Bigger, Longer and Uncut
so, it was a great v3dmm film.
