At the Grammy Awards on Monday night, Stevie Wonder presented the award for song of the year with a cappella group Pentatonix.

Before announcing Ed Sheeran as the winner, Wonder took a moment to poke fun at the other presenters. The winner card was written in Braille script, so only Wonder could read it.

Check it out. This Vine of moment was posted to Twitter by New York Times reporter Dave Itzkoff.

"You can't read it. You can't read braille. Na-na-na-na-na-na," Wonder taunted the crowd as he opened the envelope to announce the winner. The award went to Ed Sheeran for "Thinking Out Loud."

Wonder then followed his joke up with much more serious statement.

"We need to make every single thing accessible to every person with a disability," Wonder concluded.
