Every May, the internet is bombarded with commencement speeches recorded, uploaded and quoted. Famed celebrities, media moguls and rich businessmen flock to college campuses to inject some sense of hope into young and anxious soon-to-be college graduates. Here are the top 5 moments in this spring's commencement speeches. This year, the college greens were graced with the presences of: 'All Of Me' singer John Legend, Oscar-winning actress Sandra Bullock, the host of NBC's 'The Tonight Show' Jay Leno, 'It's Always Sunny in Philadelphia' star Charlie Day and the recently-fired New York Times executive editor Jill Abramson.

1. John Legend Parodies 'All Of Me'

Yesterday John Legend delivered a heart-warming speech at his alma mater, University of Pennsylvania. As he discussed his new-found popularity as a solo artists with the song 'All Of Me', he decided to give it a new whirl by giving his song new lyrics.

"I've had a 10-year career as a solo artist and none of my songs has ever been one of those [top] 10 songs. Until this moment. And now "all of you, are so over me, you're tired of hearing that I went to Penn. Why'd they bring him back again?" (sung to the tune of "All of Me" chorus)"

Here's John's selfie right before taking the stage in his robe:

And he talked a lot about love. Do what you love, love what you do, love who you are, and love who you're with. Quite appropriate for a musician with an album named 'Love in the Future'.

2. Sandra Bullock Surprises a Louisiana High School

'Gravity' star Sandra Bullock surprised a group of graduating seniors at a Louisiana High School with her presence this May. She has been giving major financial support to the school ever since Hurricane Katrina destroyed the school.

The wisdom that she imparted on the graduates? "Eat something green every day with every meal," and "Do not pick your nose in public."

3. Jay Leno Shares 12 Rules of Show Business

Jay Leno, the popular host of 'The Tonight's Show' and a staple in American late-night show culture, returned to his alma mater Emerson College to dole out 12 tips on succeeding in show business. He said to "never go on stage mad" because "anger robs creativity." Another one? "Don't judge your own success by the success of others," he said, "everyone's road map charts a different path".

4. Charlie Day Says Not to Give a Shit

"I don't give a shit," Charlie Day, the star of 'It's Always Sunny in Philadelphia", said. And the student roared into applause. "You cannot let a fear of failure, or the fear or comparison, or the fear of judgment stop you from doing what's going to make you great."

Day was also awarded an honorary doctorate during the ceremony. "I can't wait to start writing prescriptions immediately," he joked.

5. Jill Abramson Also Doesn't Know What to Do with Her Life

Jill Abramson, the ex-executive editor of New York Times, has recently been under media scrutiny over the sudden leadership change. "What's next for me?" she said. "I don't know, so I'm in exactly the same boat as many of you." Good thing she retained her sense of humor!
