As for slacking on the weekdays - Perl!
Unless a new video game strikes my eye :)

Last one was Thief 2:
In between jobs a while back, I acquired my work
'puter for a good price. I installed Window98 on
it (without even formatting the partition properly
from its previous Red Hat installation) just so I
could play Thief 2 for a whole week

When I finished it, I put Red Hat back on it and went
back to tinkering

Since I can't play any new games on my antiquated Winders
box, I'll have to be content with . . . .

MAME!!!!
