Watch Glee Season 1 Episode 18 - Laryngitis

Summary: A sore throat impacts Rachel's singing; Kurt tries to impress his father; Puck hopes to elevate his social status.

A lot of big changes are happening in the next episode of "Glee". Puck makes the biggest move, shaving off his mohawk and seducing Mercedes in a bid to elevate his social status. Smelling something rotten in the air, Mercedes snaps, "I'm gonna ask you to stop!"

Meanwhile, Kurt tries to change his persona to impress his father. This means, taking an advice from Sue Sylvester and hooking up with Brittany in the basement. Rachel panics when a sore throat affects her singing and the doctor jokingly says she can't sing anymore.

In a spoiler by TV addict, it was said that Kurt will do two big solos, one of them being "Rose's Turn" from the musical production "Gypsy: A Musical Fable". Finn will also get his solo piece, singing Rick Springfield's "Jessie's Girl".
