Well, I know that you have performed your show, and I'm glad that you succeded, but in the very first post you ask what forced humor is, and how you know that it is forced and if it any good.
Well I personally think that it is okay, if you have some few planned funny remarks, this I do myself. Not say'n that all people always laugh when say'n those planned remarks, but in general you will succed, and the only way to come up with something funny which is matching the effect that you are doing, is to try them out and see how people react. I know that many people will dissagree with me, and say that the humor want be any good if it is planned, and that is has to be natural. Of course do not make every effect funny, but it can be quite good to have some funny stuff once in a while - but still it depends how you are as a person and how you want your audience to see you.
My advice is, take your time in finding some funny remarks which matches a few of your effects, and then try it out on the street, to see how it works and then you can make some changes if necessary. (some times you get some performing tips when purchasing effects with a video torturial)
Take it or leave it

but I have had great succes with planned humor
