Baldwin donned a fake beard and top hat to disguise himself as U.S. President Abraham Lincoln when he surprised a history class at Occidental College in Los Angeles.

The former 30 Rock star delivered a humorous rant on media and civil rights and took a selfie with the class before posting the snap on his Twitter.com page.

The surprise visit was part of car company Chevrolet's #BestDayEver campaign.

Olivia Wilde also participated in the promotion and unexpectedly shared her insights with young students training to become production assistants in New York City.

Wilde spoke of her own journey, admitting she was "the worst PA".

Meanwhile, The Walking Dead's Norman Reedus was also in New York City to surprise St. John's University students, and newly engaged couple Nikki Reed and Ian Somerhalder spent their morning in a business class at Atlanta, Georgia's Emory University, discussing promotion and branding.
