Substitute teachers had their own brand of charm — and a go-to set of phrases we all remember. Whether they were trying to maintain order or just survive the day, these one-liners became the soundtrack of every unexpected sub day. Here’s a nostalgic look at the 10 unforgettable things every substitute teacher seemed to say.
1. “I’m not sure how your teacher normally does it…”

This was the ultimate disclaimer. It let them off the hook for everything, from the lesson plan to classroom rules. You knew the day was about to be a free-for-all.
2. “Let’s just watch a movie.”

The golden words every student prayed to hear. A sign that the sub had given up or was feeling generous. Either way, you knew it was going to be a chill day.
3. “Your teacher didn’t leave me any instructions.”

This one sparked instant chaos. Whether true or not, it gave students the green light to test boundaries. Suddenly, everyone “forgot” what they were supposed to be doing.
4. “Is that your real name?”

Used after reading a clearly fake roll call answer like “Sir Lancelot.” Every sub got punked at least once, and this phrase came right after. Some laughed, some got mad, but it always happened.
5. “I’ll write your name down for the teacher.”

The ultimate threat — but no one ever saw the consequences. Still, it had just enough fear factor to calm the class down temporarily. It was like getting a yellow card in soccer.
6. “Let’s take attendance…”

This was always said with an unsure glance at the sheet and a sigh. Cue mispronunciations, long pauses, and groans from students correcting them.
7. “This isn’t my usual subject.”

This was said either to excuse confusion or lower expectations. You could tell they were winging it, especially if they started reading from the textbook.
8. “Let’s just get through the day.”

The sub’s survival motto. There was no sugarcoating, just honesty. Everyone appreciated it, even if it meant doing absolutely nothing. It was a vibe.
9. “I’ll be here all week.”

This was met with instant groans or cheers, depending on how the first day went. This phrase meant you’d better start behaving — or plotting. Either way, it changed the dynamic real quick.
10. “I used to be a teacher.”

This was a phrase meant to establish credibility, but usually led to a tangent about the good old days. It didn’t help with discipline, but it gave you a glimpse into their past.
