Action man DWAYNE 'THE ROCK' JOHNSON joined forces with funnyman JIMMY FALLON for a skit on the TV host's THE TONIGHT SHOW STARRING JIMMY FALLON, during which the stars dressed up as graduating high school students and delivered the worst commencement speeches ever. The pair donned wigs and the traditional cap and gown attire to attend the ceremony for Oneonta High School's Class of 1989, and belted out a verse of Bon Jovi's rock classic Livin' On A Prayer to celebrate their academic achievement, despite coming bottom of their class. The segment aired on the show on Thursday (21May15), at the height of graduation season, just hours after Jon Bon Jovi had been handed a Doctor of Letters honorary degree from Rutgers University in New Jersey. Bon Jovi also performed at the ceremony.
