Microsoft, Solaris and Linux Programmer

There were three programmers one was working for microsoft, one for solaris and one for linux they met at the toilet:

The one from Microsoft used tons of paper and tons of liquid soap and said:
"Microsoft teaches us that we can use lots of resources that the work to be good"

The one from Solaris used a littel paper and soap and said:
"Solaris teaches us that the resources should be preserved and the performance grows up to 90%"

The one from linux uses no paper and said:
"We the programmers from Linux have learned not to piss on our hands"
