<human>: So i'm taking a 2-D design art class this semester, and we work mostly on  mac computers. The teacher gives roughly a 4 hour lecture with the use of "Screen share" which allows her to as it suggests share her screen to our computers. Now a friend and I want to really mess with this teacher because she is 1. out of her mind, and 2. completely boring. We thought it would be funny if we could somehow while she's screen sharing all the computers, that we somehow be able to also control the screen and basically mess with her by moving the mouse slightly, or drawing obscure things she wouldn't usually do while she's trying to give a demonstration to the class on what needs to be done. Now if it's even possible, i also want to know if we can get her to do a screen share, but everyone else is screen shared to my computer, and i'll do my best to go along with what she's saying, but add more humor and innuendo to it.

Provide a brief overview of the text.
<bot>: I'm looking for someone who knows how to allow my computer to intervene the teacher's computer when she does screen share.
