Linsanity has reached the retail world.

Jeremy Lin apparel has been flying off the shelves in stores, in Madison Square Garden, and online.  Lin jerseys were even sold at Harvard’s Lavietes Pavilion during the Harvard vs. Brown Men’s Basketball game on Friday night.

But, for one important spectator, sporting a classic Knicks Jersey was not enough to show his Lin pride.  Spike Lee, an avid Knicks fan, decided to go old school.

On Friday night at Madison Square Garden, Lee was spotted wearing green, rather than blue and orange.  Lee had made special arrangement to wear Lin’s high school jersey.  Before the Knicks and Harvard Basketball, Lin was number 4 on the Palo Alto High School basketball team.

According the Wall Street Journal, Lin’s high school coach, Peter Diepenbrock, had joked to a radio station in the Big Apple about dressing Lee in Vikings apparel.  Lee was excited about the idea and made it happen for Friday night’s contest against New Orleans.  Lin and Lee greeted each other briefly before the game.

It seems that the reminder of Lin’s high school days was more of a curse than a blessing.  The Knicks seven-game winning streak was broken in a close loss to the Hornets.  Lin scored 26 points and made five assists in the contest, but also committed nine turnovers to cement the 89-85 loss.

Lin and the Knicks take on the Dallas Mavericks on Sunday at 1:00pm at Madison Square Garden.
