Holy crap, who is this person and why does he have a microphone? I feel like we need some licensing regulations before people are allowed to purchase microphones.

Clearly, you're not online enough: He is a tenured professor at Stanford.

Is he not getting enough sunlight within 2 hours of waking up?

Give it your 120% effort

Maybe in applied econometrics course where they teach linear probability model? 😀

“Would take you to 120 percent, which is a different thing altogether.”

Ah, the classic "gonna make this very simple" card, which magically allows you to make shit up.

Really embarrassing. Anyone with even basic stats knows you can't be over 100% probability of pregnancy, so this person would be already pregnant once, with a 20% chance of having twins

To make this very simple, all we need to know is the probability of getting a tail in a one-attempt coin toss is 50%. So, if that didn't occur the first time, one should repeat at least 2 or probably 3 times before concluding that something fishy is going on.
