when everyone is watching for tests and you're watching for fun
i like to study while i run. when he screamed i literally almost flew off the back of the treadmill.
When your psych professor directs you to a video for homework that you've already watched because you're a nerd.....
When this is now your psychology class.
This is an amazing video to watch on LSD. Edit: Just got to 8:35. This is not an amazing video to watch on LSD.
That awkward moment when a guy on the internet is a better teacher than your Psychology professor who has a Doctorate in the field. Hank, I could not pass this course without you. Thanks.
Is it bad that I didn't even flinch when he made the jumpscare?
Who's here not because AP exams?
Get out the comment section a pay attention, you have a test tomorrow 😑
“Dear Hank, I think that you should maybe consider removing your hand from the burner, I mean, it doesn’t really feel good, you know what I mean? I love you. Love, endocrine system.”
I have ADHD and I wasn't even focused on the video... until 8:33, it snapped me back into reality
I was listening to this as I was going to bed, why would you do this?! 😂
dont watch this wearing headphones.... god i cried....
i wonder how many ap psych students are watching this rn
Studying for the AP exam tomorrow like
Dude you are a legend. You can literally make anything interesting to learn with your sense of humor. Keep it up!
I was making a sandwich when Hank did that jump scare... RIP sandwich
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!
Scrolled to the comment section just to see ppl talk abt him screaming
8:33 RIP headphone users. Your welcome :)
