Only Oprah could make the usually calm and collected Pharrell cry on national TV.
As the two were discussing his undeniably catchy song "Happy," Oprah paused to play a video of people all over the world dancing and singing to the song.
Pharrell was a little overwhelmed with joy.
Of course P's first reaction was, "Why am I crying on Oprah?"
And Oprah was like, "Well, I'm Oprah. It's what I do, duh."
"It's overwhelming, because it's like I love what I do..."
"... and I just appreciate the fact that people have believed in me for so long that I could make it to this point to feel that," Pharrell said.
