Way Too Much Joy in the Gospel?

Normally I don't bother with liturgical abuse, but this was so completely over-the-top, I have to share.  Hat tip to Brandon Vogt for sharing this on Facebook.

Apparently this is the Gospel Procession at a special Mass in Brazil.  The commentator keeps going on about "allegria" (joy) - but somehow that understates the sheer craziness of this spectacle.  Way, way beyond the bounds of enculturation... even for a country where Carnival is a way of life.
