Glee Season 1 Episode 3 : Acafellas
Will forms an all-male a cappella group called the "Acafellas", neglecting the glee club in favor of dedicating his time to the new endeavor. After two of its members quit, glee club member Finn and his best friend Puck join. The group records an album and performs at the school PTA meeting in front of celebrity guest Josh Groban, but Will ultimately recommits to New Directions. In his absence, the club members struggle with choreography, and resist attempts at sabotage by members of the cheer squad. They briefly hire well–known choreographer Dakota Stanley, but fire him when he belittles their appearances and abilities. Mercedes harbors romantic feelings for Kurt, who comes out to her as gay.
