If I'm talking about something I want to do in the future I usually start by sayin
'Some day, and that day may never come...'.

Or 'Leave the gun, take the canollis' often gets substituted with whatever two words are appropriate at that moment.

I have a wedding to go to soon and might congratulate the bride and groom with a wish that 'their first child will be a masculine child' I don't think they'll realise what it means though!

"My wife was weeping before she fell asleep, outside my window I saw my Caporegimes coming to the house and it is midnight. So, Consigliori of mine, I think you should tell your Don what everyone knows."
