Tai mentioned Dolph the other day as a guy that always says thank you and months ago I saw photos from a video production company showing that they shot a video together at Tai's house but I am not sure it was ever released.
I don't know how Lopez came into the scene but they've been hanging out quite a bit lately, after they shot that workout video/interview: https://www.facebook.com/DolphLundgrenO ... 5787088559 (I didn't know who Lopez was but apparently he's some kind of entrepreneur/business guru who became a millionaire and now sells conferences and stuff on the subject)
Tai is a bit of a controversial guy. Somehow, he got super rich and now he is trying to be a Tony Robbins type. He spends a lot of money marketing on youtube.
Some of his stuff is pretty good though.
Here are some funny videos making fun of him though.
