sonic screwdriver

Story time

So today in my theater class my teacher was showing us scenes from a play he wanted us to analyze but suddenly his computer started freaking out and the screen froze and was glitching and he just looked at me and smiled like lol what have I done
But I jokingly signaled for him to use his sonic screwdriver that he keeps in his drawer so he got it out and pointed it at his computer and I swEAR HIS COMPUTER JUST STARTED PLAYING THE VIDEO aGAIN and he looks up at me with the most AMAZED EXPRESSION OMG I LOVE IT
