Don't get what is so funny about killing some random guy that is much lesser geared than you are for no reason what so ever. If is is a dick that really asked for it it could be funny and if he out-geared you if could be really funny. Most of the gankings I see are just some 600++ hp attacking some 350ish fresh 90....sad and pathetic.
If you want funny, try being a lvl 56ish Druid back in 05 when druids were free honor. I got attacked by a very geared 60 warrior and did what druids could do best.... RUN! The idiot ran after and followed me into a lake in EPL. I went down and he kept coming. Once we are deep down enough, switch out of seal form and /cast roots, /laugh, /cast roots, /laugh, /cast roots, /laugh. Watching that warrior drown was without a doubt the most fun I have ever had in WoW.
...and in case someone was wondering, roots was one of the last forms of CC to get diminishing returns.
