What Wikipedia says: "In 1995, at the age of eight, Lamar witnessed his idols Tupac Shakur and Dr. Dre, film the music video for their hit single "California Love", which would later prove to be a very significant moment in Lamar's life." - Wikipedia

Kendrick Lamar was on the "California Love" video set at age 8, according to his Wikipedia entry, which is the best thing ever. Ever! Headlining tours, getting a surprise remix of your song by Jay Z, causing an industry earthquake with your own guest verse, getting nominated for an Album of the Year Grammy? All of those things pale in comparison to being a second grader on the music video for one of the best songs and videos of all time!
