This draft is better, but that particular sentence sounds ridiculously immature.
"Yeah, Jenny, call the NBA, tell them I can't make it tonight, I am gonna, uhm... research this community and, uhm... technology and then I am gonna, uhm... join The Movement and start twitting about it like crazy. Maybe order some billboards for them."
Busy famous people like to know why they're being contacted and what we're hoping to get from them. This sentence shows that we want nothing more than his goodwill and perhaps a public endorsement. I.e. we aren't trying to get financial support from him, manipulate him, or call in favors at a later date. Maybe it could be reworded, but this message needs to be conveyed. I also wanted to indicate that we aren't naive enough to think he'll jump in without researching first. I'm sure he researches all his investments very carefully.
