Pharrell Williams was fired from McDonald's three times when starting out.
"At a certain point they just realized that I was no help," Williams said on "Late Night with Seth Meyers." "I was only good at eating the chicken nuggets."
The funny thing is, Williams would actually become an important figure in the chain's history — he co-wrote the Justin Timberlake song "I'm Lovin' It," which became the basis of the iconic slogan and jingle.
