What did your teachers used to say when you misbehaved?

Whenever I, or my entire class decided to misbehave, they would always use the same phrases.

Primary 3/4: "You guys aren't in lower primary anymore, no more playing, if ya'll continue ah, then I will call your parents and they will cane you at home (they didn't actually call our parents at all).

Primary 5/6 "PSLE is next/this year, if you don't listen you will fail , I guarantee."

Sec 1/2 "You're not in primary school anymore, stop acting like little children."

Sec 3: "You're not in lower sec anymore, Sec 1 Sec 2 just play, but this year you need to buck up cause' your O level is next year. Don't come crying to me when you fail ah.

These are probably the most common ones I've heard throughout the years, but what have your teachers said to you?
