Aside from the Yamanote-sen eki, I understood maybe 1/3 of it.
And it was hella funny!! BEDDO! DOUBLE BEDDO! TA-KA-DA-NO-BA-BA!
A nice touch was that the instructor spoke kanji, hiragana and katakana when appropriate and the class, for the most part spoke katakana. Like real Japanese language classes...
SHIN-BASH!
