As President Barack Obama delivered the commencement speech at a Michigan high school's graduation ceremony, not everyone was paying rapt attention.

One member of the Kalamazoo Central student choir sitting behind the president had some serious trouble staying awake.

In videos posted online, the boy is seen succumbing to a series of gaping yawns as Obama offers advice on how to succeed in life. Later, the boy's eyes droop and his head rolls forward until his chin rests on his chest, and it appears he has nodded off.

Only occasionally is the unidentified teen jolted into consciousness as his classmates erupt into cheers and applause for the president.

Obama delivered the school's commencement because it won the Race to the Top Commencement Challenge competition.
