...is this a joke, or is it serious ? ...
I think it is a joke and a rant about folks doing the kind of stuff he describes in his neighborhood.
...Do you want to know how cool your bike looks or what it sounds like when it's revving out as you go zooming up the street...
...whole little costume...
...pretend I am in a race with myself on your bike and then you will know how cool you look when you are whipping up your street past all the kids....
...get some bleach and pour it on the rear tire when I am doing it and all your neighbors will think you have a top fuel dragster or some #$%* when they see all the smoke...
...I really don't want to ride anyone on the back when I do this for you so don't have any girls around...
These all say joke/rant to me.
