I hope you're OK and there aren't any assault charges or liability issues I have to concern myself with.

I had all but given up on understanding the meaning of "caiu a ficha" - "the penny dropped" - it's some god-damned Brazilian idiom.
It's a kind of an epiphany statement like "then it hit me!".
XPT Example:
"I couldn't figure out how that ugly talentless slut got a nomination over Mia Rose but when I saw her rubbing up on Mike Ramone
the penny dropped!"
