"With athletes and viewers exhausted, the closing ceremony for Rio2016 was passing off as expected... Until Japan's Prime Minister Shinzo Abe popped out of a giant green pipe dressed up as video game character Super Mario, one of Japan's best-known exports. It was then the world got a clue that, for Tokyo2020, the next Olympic hosts would take full and shameless advantage of Japan's pop culture icons.
Abe making pipe-dream a reality
The Tokyo2020 video beamed to audiences in Rio showed Mario running excitedly around Tokyo then jumping into his famous green pipe."
I have watched the whole closing ceremony and I have to say this was the funniest moment. I can't wait to see what Japan has prepared for its own ceremonies.
