Need ideas for video editing topics.

Im really into creating videos right now with sony vegas 13. I have made a bunch of AMVs and clips of like random funny youtube footage but I want to focus on more real serious stuff but don't know what to do.

I don't have a camera right now but plan on buying the gopro cube which will give me unlimited ideas, but right now im basically taking random clips off other youtube videos and making edits with them or making AMV's.

My goal for videos right now are to trip people out and be like what the fuck did i just watch,
but im tired of making AMV's. So what should i do? any ideas on what topic i should edit on? just throw me random ideas that i should do from government corruption videos, editing other music videos, idk. thanks.
