I noticed this like fifteen minutes ago:
In the little intro for "SportsCenter" on Dedication 2 (2006), Wayne talks about how he loves sports, and does not even mention skateboarding (hockey is mentioned).
I want to be clear in saying, I am not mad at Lil' Wayne for skateboarding, people who have skated with him all say he seems to genuinely love it. However, his claim that he has been skating since age 14 or whatever he said is clearly bullshit.
Anyone who has seen him on the board can glean that fact though.
