THESE AREN'T JOKES

This movie is currently a huge meme in china. It came out of nowhere and inexplicably got a theatrical release, looks like ass, was animated completely by the director and his mother, and took several years to make. "Niu Lai" translates roughly to "The bull is coming" and apparently the film has several other allusions to stock market puns. The Chinese stock market coincidentally had an uptick the day of its release which added further fuel to the meme fire. After going viral Niu Lai began to actually turn profit at the box office, theatres unprepared for Niu Lai mania (the creators did not distribute any promotional material) had to improvise DIY posters:

Back when I worked at the hospital, I had to take MRI training and it was my favorite thing every time. It was only like 10 minutes long and went a little something like this:

Hey. The MRI is basically a really big magnet and by basically I mean it is and we literally never turn it off. It's like really big. Really really big and powerful and The Magnet is always on. We don't turn it off Ever, for any reason. We mean it bro, The Magnet is literally always on. It's crazy strong and will definitely kill you. So don't bring any metal into the MRI room, man. You will fuck up the machine (because The Magnet is always on) and then you will die (again, because The Magnet is always on). Here's some fun questions for you to test your understanding!

1) The ______ is always on.

2) The Magnet is ______ on.

3) How often is The Magnet on?

4) The Magnet is always __.

5) The Magnet is always on. T/F

6) The Magnet is usually on but we know to turn it off for you because you're a very special boy :) T/F

7) My weak fleshy body can survive the wrath of The Magnet. T/F

8) Look at this 500 lbs steel hospital bed, which The Magnet has crumpled into an origami crane. Imagine if that was you.

9) Is The Magnet ever off?

10) Sometimes we turn The Magnet off. T/F

Thank you for taking MRI training. We hope you learned that The Magnet is always on, because it is. It's on Right Now and it will be on every time you come to the MRI. Have fun and remember: The Magnet is always on!

This is a given.

If the last digit is divisible by 2 (a.k.a. even), then so is the whole number.

If the sum of the digits is divisible by 3, then so is the whole number. The recursivity of this means that if the sum has multiple digits, you can add them up again until you get a single digit and see if it's 3, 6, or 9.

Like the rule for 2, but check if the last two digits are divisible by 4.

If it ends in 5 or 0.

If the rules for both 2 and 3 apply.

No shortcut. Alas.

Like the rules for 2 and 4, but check if the last three digits are divisible by 8. (Yes, this pattern keeps going for 16, 32, etc.)

Like the rule for 3, but the sum of the digits (or the sum of the sum of the digits, etc.) must be 9.

For example, 294

29 4

4×2=8

29-8=21

21 is divisible by 7

Second example, 1946

194 6

6×2=12

194-12=182

182 is still large, so let do it again

18 2

2×2=4

18-4=14
