The actor ditched his sweats and baseball cap for a more clean-cut appearance to promote smart-drink, Liquid Focus.
In the video, Oliver was wearing a wire-framed pair of reading glasses and a black sweater and said he was sporting the "fake" eyewear and, "Steve Jobs turtleneck" to look smart!

Oliver regularly delights his devoted followers with his amusing social media antics.

When his sister, Kate Hudson was nominated for a Golden Globe, he didn't congratulate her in the traditional way, but instead posted a comical, crying video.
The father-of-three was seen giving an impressive performance as he pretended to get emotional about the fact that both Kate and his sister-in-law Meredith Hagner – who stars in Palm Springs, which is up for Best Picture, Musical or Comedy, had been recognised, but he hadn't.
He usually has a more casual style
Oliver wrote: "Didn't get nominated for a Golden Globe today.. Congrats @katehudson and @merediththeweasel .. I guess... You 'earned it'. You both were so 'deserving'. Thanks for nothing @goldenglobes."
It wasn't just his fans who found it hilarious. His mum had the best reaction when she commented: "Oliver, Oliver!!! I can't stop lol. Omg."
