Andrew Harrison playfully shoves twin brother Aaron in NBA summer league game (video)

Andrew and Aaron Harrison are making their NBA debuts in the 2015 NBA Summer League, and they're already getting chippy with each other.

Aaron, now playing for the Charlotte Hornets, is facing younger brother Andrew, who's playing for the Memphis Grizzlies, for the first time in their lives. In their first summer league game against each other, Andrew gave a playful shove to Aaron when the older Harrison attempted to shake his brother's hand.

Expect noted Harrison-hater Jeff Goodman to point out how bad of a kid Andrew is for pushing his brother.
