I've been watching crash course for a few years now but I can't believe it's now actually helping me more with my psychology degree than the textbooks my teachers assign. Thank you Hank, hope you know these videos, even years later, are getting some of us through entire college courses
Its crazy how I grew up watching Crash Course and now Im watching yall again in college😅
The jumpscare scarred me for life!🍃💩 Not again-😵
i watched that "AHHHHHHHHHHH" several times
"Here you go SIKEEE!!!" 4:15
When studying for my AP Exam, when he screamed, it made me start dying😂I couldn’t stop laughing, the timing just made me, lose it. Lmao 😂🤣
I died laughing when he did that scream. I’m different like that
These crash courses are a godsend for those with ADHD. The visuals really enforce the absorption of the information by keeping my brain stimulated and engaged. The screaming helped too lol. Thank you for the lesson!
4:14 funniest part of this video
I find Psychology fun, most people do not. You made the most intellectual study fun for everyone, you my friend are a genius
8:35 exists me with subtitles - You have no power here
Well let's learn about psychology in this quarantine.
When our mom says you can only watch educational videos “Laughs maniacally”
Scrolled to the comment section just to see ppl talk abt him screaming
When this is now your psychology class.
I'm more focused on amazing his shirt is than the actual content
That scream tho. So funny lol.
i like to study while i run. when he screamed i literally almost flew off the back of the treadmill.
This is literally a week of my school lesson in one video.
I was recapping this for an exam and I am too tired for the scream to scare me. I’m even wearing headphones. My body just did not care
