In no special order -just the best I can remember even now.
Green Green
Absolute humour and raunchy romance to boot. Also, there just might be a *real* love-triangle in the end -one can only hope.
Outlaw Star
If you can ignore the horrible ending, several anomalies in the plot (like the protagonist getting shot in one screen then being like nothing in the next), and space-ships with arms so they could shoot with gigantic pistols -instead of their "normal" laser-vulcans- you can find a really entertaining anime.
Love Hina
Again, if the end is ignored this is another great anime -if you are into harem-stuff.
Tenchi Muyo!
Much like Love Hina, but a bit better thanks to the "demon." Some anomalies in this one too and their relationships do not seem to go anywhere, but good nevertheless.
Buttopi CPU
It's just perverted in a right way.
