If I was a real man, I'd be able to multi-boot to 37 different OSs on one box... 
All I can say.....actually I could say a lot, but I'd have to say;
UBER GEEK!!! 
I use multi booting because its impracticle (and expensive) to have a multitude of boxes, yet I need to remain compatible with work committments. I want to explore and learn Linux (and other) o/s's, and don't yet know which one is for me. But 37 o/s's is definitely at/over the top.
That means I could run several versions of FreeBSD 
Sorta like 4.6.2, 4.7 and the expected 5.0; and NetBSD; and RedHat; and ....
:rolleyes:
