This has nothing to do with Mondo Reale at all, it's just a "funny" sentence as part of Gigi's anouncement ;) It is partly written in Brescia dialect, so that may be why the translator had trouble (me sò = mi sono, dù = due). "I've finished the rhymes and have broken the... ...two buttons... of the shirt..." (normally "me sò'rotto" or "mi sono rotto" is part of Italian sayings with often rude language, but Gigi replaced it with something harmless)
