Got my students earlier (twice)
I was demonstrating for a physics lab today and we were doing an electricity experiment, building circuits and measuring voltage and current with various configurations of resistors.
One pair asked me to look at their results so I picked up the paper and started to shake my head with a scowl on my face.
Girl: What is it? What's wrong?
Me: It's these results.... they're shocking...
After a second of being genuinely worried, they realised I was laughing and looked at me angrily.
Guy: That was terrible.
Me: Sorry, I just couldn't resist.
Cue Groans
