Imagine sitting in an 8:30 a.m. marketing class trying to wake up. Then… cameras. Lots of them. “Guest speakers,” your professor says.

But these aren’t representatives from some Fortune 500. Wednesday actors Ian Somerhalder and Nikki Reed surprised an undergraduate class at Goizueta Business School by stepping in for marketing professor Manish Tripathi. The duo took questions about personal branding and shared some general good fun through Chevy’s #bestdayever campaign.

Other celebrities, including Alec Baldwin surprised students in similar fashion at universities and colleges around the country.
