This is for BillyBob:
I’ve noticed the distinct lack of humor on this site (with the rare exception of outlier BillyBob).  In honor of BillyBob, I’d like to pose this question:
Is Black Belt sense of humor a normal or a folded normal distribution?

Itz a bimodal distribution, with one segmented group like u & me , so to say humorous and the others less humorous !!!!!!

Let’s see if we can get creative here….
How many black belts does it take to change a light bulb?

The light bulb will not be changed unless you can prove that the hard savigs of changing it are grater than the cost, something hardly possible with the hourly cost of the black belt that has to change it!

Zero, BB’s do not change light bulbs.  But they can help to get it changed, by first having the Green Belt, count all the lights that didn’t go out.  Then develop a chart that shows when light bulbs do go out ( assuming that lights are not turned off, else they have to chart the time lights are on with respect to the time lights are off.  Then test the data by waiting for additional lights to go out.  Then change 1st all the lights that are going to go out but havent, then change all the lights that have been out.  Since this is attribute data (light are either on or off, blinking lights are considered on until they go out), no special Ppk or Cpk calulations will be necessary.

Why even bother to change the bulb. A customer kept in the dark complains a lot less than an en”light”en one

Actually it is a Student -t distribution. (due to extremely small sample size as few BBs will change a lightbulb.  Even above their own desk).
(Bell shaped and symetrical but lower at the mean, higher at the tails.)
Extremely small df value for the same reasons.
I am also a BillyBob fan
