As the saying goes, hindsight is 20/20.

This episode featured Glee’s first try at original songs, including the smash hit "Loser Like Me” … But let’s just say the cast didn’t love the song at first, and even tried to get Ryan Murphy to cut it from the show!! Kevin and Jenna relive the "embarrassing" behind-the-scenes moment when they confronted Ryan.

Plus, Kurt and Blaine finally kiss, and it's one of the best first kisses in TV history!! Facts.
