  • Only ep of crash course that has in-vid bloopers

  • Interesting thing happened to me about a year ago. I was in bed when I heard an odd rustling noise. It wasn't a fly nor the pittering of a rat, it was a cockroach. Prior to this event, roaches would scare me as much as a crocodile or a Bobcat would. I'd be alerted by them but eh it won't send me running.

    I got so scared I ran to my mom and since that day, the scurrying popped out in my head. If you take any shape similar to a roach, I will detect it with alarm but not fear it outright.

    Once that specific scurry reaches my ears, I react before I even see it!

    It's an interesting shift in perception where it used to be

    "A wierd thing?"

    And it's now more like "AAAAAAAAAAAAAA ROACH!!!!!"

  • RIP Dr. Sacks πŸ™


  • K S

  • Youu know you watch too many kpop when a korean ad pops up before the video shows…. I'm here to watch and learn not to get distracted and feel the urge to watch kpop :/ … not like i'm feeling that way hahaha

  • "Sherbert" is an example of the Mandella Effect.

  • That is one quality doggo.


  • I just had to watch the start of this video over because i got so distracted by the dog that i forgot to listen lol


  • Sorry. I'm worried that the only thing I can remember is the Corgi, sooooo cute.

  • At 3:05 is that John's family? (I LOVE finding little Easter eggs here and there)

  • Wow! Thank you so much! I've been unsuccessfully trying to decipher the chapter on vision in my textbook for an online class in sensation and perception. This 10-minute video cleared up a great deal of what I wasn't understanding.

  • I am listening this because learning I am curios and this is awesome.

  • PUPPY!!!!!!
