Before the Deepavali-Aidilfitri vacation I had zero experience working with a Linux machine. Some time fiddling about with Ubuntu in Pasir Mas changed that. (Not by much, but some.)
I wouldn’t have understood this joke before three weeks ago, so don’t feel bad if you don’t get it. When I saw this one on RPG.net it really cracked me up. I have no clue who made this or where it originated, though.
