MrProper

I was cleaning up an old version of the kernel and I came across this command

 make mrproper 

Curiosity got the better of me, and I went ahead googling and fell on a forum thread discussing the origin of the “mrproper”. After “analysis", it was found and confirmed that mrproper stands for “Meister Proper” (German) or Mr. Clean , a cleaning liquid product.

Hmmmm……
