Now the YouTube sensation can add t-shirt entrepreneur to his list of credits.
Gavin's mom Kim Justice, copyrighted the saying, "he my team" after getting numerous calls from interested companies, she says she never thought she would be in the t-shirt business.
"Two separate companies that had called me on the same day, wanting to copyright the phrase 'he my team.' I hadn't really thought about anything like that, but talked to my family and we kind of decided as a family that it was probably best for us to it ourselves," said Justice.
The "M" and "Y" standing for Michael Young, she says its a way to show Young and the Rangers support this season.
So far they have sold several hundred shirts, and counting. With Young still on the team, Gavin has more than one reason to smile.
The family plans to donate a portion of the sales to one of Young's favorite charities "Wipe Out Kids Cancer."
