A LITTLE MORE HISTORY ABOUT THE NY RANGER / NY ISLANDER RIVALRY FROM WIKPEDIA .With both teams' fans visiting "enemy territory" for games, organized shouting matches and fights break out in the stands. Fans will direct derisive chants at their rivals regardless of whether the teams are actually playing. At each home game, Ranger fans engage in perhaps their most popular chant: humming the song "Let's Go Band" and punctuating it with "Potvin sucks", referring to retired Islander Hall of Fame defenceman Denis Potvin. Rangers fans also occasionally bring out the chant "Beat your wife, Potvin, beat your wife", a reference to unconfirmed allegations that Potvin has committed domestic abuse.
Islander fans taunted Rangers fans for many years with the chant "Nineteen Forty", referring to the Rangers having the all-time longest drought without winning the Stanley Cup, until the Blueshirts finally won in 1994. For a period in the late '90s and early 2000s, Islanders fans would punctuate the "Chicken Dance" with chants of "the Rangers suck", but in recent years the song has not been played. Blueshirts winger Theoren Fleury used the chant as an excuse for flapping his arms to taunt Islanders enforcer Eric Cairns. In addition a popular chat was "Crackhead Theo!" referring to Theoren Fleury's erratic behavior and history of substance abuse at the time. Islanders fans also sing a song to the tune of "If You're Happy and You Know It", replacing the standard lyrics with "If you know the Rangers suck, then clap your hands."
One well-known incident at an Islanders/Philadelphia Flyers game in 2003 turned an innocent holiday promotion at Nassau Coliseum into an on-ice brawl between Rangers and Islanders fans in Santa suits. The Islander management invited everyone in Sant suits on to the ice between periods , well a couple of these Santa's were RANGER FANS and when they opened their Santa jackets revealing their Ranger jerseys all hell broke loose . Then there was the infamous banner incident I've mentioned before .
What if someone were to go to a Rangers/Isles game wearing a jersey that was half Rangers half Isles sewn together?
