There are a lot of dudes with signs at New York Islanders games, but there's only one true Dude With Sign.
Dude With Sign - who has 4.9 million Instagram followers - brought his cardboard to Barclays Center on Tuesday night. He was there to support the Islanders and make a point, reminding people to "Stop Saying "In" Long Island.
The social media influencer had a little in-house competition, pairing up with Patrick Dowd, aka the Islanders "Sign Guy," for a collaboration. If Dude With Sign wants people to stop saying "in," then "on lawn guy land" it is.
