As Knicks fans all around the nation continue to mourn the departure of Jeremy Lin to the Houston Rockets, one fan has taken to YouTube to express his own frustration and sadness.If you find yourself depressed and feeling blue, go ahead and sing along to this humorous parody of Gotye's hit, "Somebody That I Used to Know," appropriately titled, "Jeremy Lin That I Used to Know."The guys at "The NOC TV" never fail to produce amusing clips for sports fans. They've even enlisted injured Knicks point guard Baron Davis to help out in the past. Following the initial outbreak of "Linsanity," the funny group also surprised fans with a hit called "Lin on Me."So, as you try and cope with the Harvard graduate's departure, sit back, take a deep breath, and sing along to the catchy and perhaps calming tune above.
