Seniors from Marjory Stoneman Douglas High School in Parkland, Florida - the scene of February's deadly mass shooting - are now graduates following yesterday's commencement ceremonies.
The speaker was a surprise; it was "Tonight Show" host Jimmy Fallon, who mixed humor with messages of inspiration. Fallon told the students, "You won't be classmates anymore. You'll be adults who Facebook-search each other at two in the morning for the next ten years."
