[@VapingNurse]

It's ok. We love Hank Green, too.

[@ajs1998]

Dr Sammy is my favorite Crash Course host. Charismatic, funny, and clearly passionate about the subject.

[@Topcatyo.]

The intro for this particular video in the series was top-tier

[@CaseyRae67]

The “I love you” made me scream 🤭

[@bubblegodanimation4915]

Finally! It's back!
This course helps me more on biology than any textbook or professor!

Is Hank Green was my boss or if I had a boss like Hank Green, I think I would end every interaction with I love you; HR be damned. Hes too good not to love.

Another great video.

[@Heyitzash17]

I wonder if there is a defect where the wrong type of cell has a receptor protein and what would happen?

[@Beryllahawk]

So the "crine" in Endocrine is for the message, then? Kinda cool! Never knew there was this much complexity just for me to remember to breathe!
