Java (rather by accident and a lack of insight, falling prey to some sort of OO hype). Then I switched to C and C I enjoyed very very much.

Later I was urged to do some things in C++, which I found interesting but never fell in love with :-) and later, since I had to do more sysape stuff, bash.

Maybe it's good to learn a new language from time to time to get some inspiration and this is also fun ...
