"This is the last time me and Dad are helping you. We MEAN it this time"
"What you've done so far is not so bad that it can't be fixed, as long as you turn your life around right NOW - you can still have a good life."
My personal favorite - as I clutch at my heart "I can't take this anymore, son, I mean it, I'm getting older and I don't think I can stand anymore". (For those of you old enough, I would make Fred Sanford proud).
