Well, Yes.
I had pretty much everything planned out and setup, including all presentations and scripts, written down, as Eugene always suggests.
The only part left was to thread together some effects. The rest, I leave it to my personality, to interact with spectators in real time. I usually avoid memorized jokes/one liners and let them flow naturally from me. It makes my presentation much more efficient and people can see that what I'm saying is quite genuine
Thanks again !
