The Lonely Island guys lead us through a grammar lesson about semicolons, but, uh, they're mostly hashtag-rapping.

"Semicolon" is the latest installment of the trio's "#WackWednesdays," a YouTube series featuring a new single each week, leading up to the release of their third album, out 6/11.

The Wack Album also includes features from Justin Timberlake, Adam Levine, Lady Gaga, Kendrick Lamar, and Pharrell.
