Brendan Shanahan is doing his best to make "Dart Guy" a thing of the past.

The Toronto Maple Leafs president voiced his support Monday after superfan Jason Maslakow announced he struck a deal to quit smoking.

Maslakow became a viral sensation when cameras caught him with the unlit cigarette hanging from his mouth, a Maple Leafs-blue painted face, Stanley Cup-shaped mohawk, and a blue "Go Leafs Go" shaved into the back of his head during Game 2 of the Toronto's Eastern Conference First Round series against the Washington Capitals at Verizon Center.

Maple Leafs fans went crazy for Maslakow on social media, and he received tickets to each of Toronto's three playoff games at Air Canada Centre. Nicorette Canada teamed up with Maslakow to make him a face of their nicotine gum line, which prompted his decision to quit smoking.

Fans applauded Maslakow's decision, and he announced his appreciation for the support. But Shanahan's gesture was another incredible moment for the Toronto diehard.
