(CNN) - Joe Biden couldn't help but take a dig at his boss Wednesday when one of the vice president's teleprompter screens fell down during his commencement speech at the U.S. Air Force Academy.

"What am I gonna tell the president?" Biden said as a gust of wind knocked down his left teleprompter. "I'm gonna tell him his teleprompter is broken. What will he do then?"

The off-handed quip immediately drew laughter and some the loudest cheers of day from the graduates.

Obama has long been criticized from Republicans for at times appearing over reliant on a teleprompter, even during short and informal speeches. During the White House Correspondents Association dinner earlier this month, the president himself poked fun at his penchant for using a teleprompter.

"You know I had an entire speech prepared for this wonderful occasion, but now that I am here, I am going to try something a little different - I am going to speak from the heart," Obama said jokingly as his teleprompter rose from the floor.
