cartoon based on laptops during class

This cartoon made me laugh so much because it reminds me of me when i was in class and i would use my laptop and start surfing the web or on Facebook. in this cartoon, he told his friend to stall so he can find the answer on the internet instead of just paying attention to his teacher he had to look for it online. 

Other cases are that the student is on some kind of web not paying attention to his/her teacher and the teacher will come over to check what it is. Majority of the time students get to nervous to exit the wed page or exit an unrelated activity they are doing. What i noticed on my laptops is that i can have many windows open. 

for example, i have a mac book pro, i can have Facebook, iTunes and even my email open on one window. and if i slide three fingers to the right it looks like i have nothing open because its a empty screen, but my open stuff is on the other screen so in order to back to it i slide three fingers to the left. I have used this a couple if times so my teachers would not look at the stuff i have open. I usually have like an article related to the class on the screen.
