MILWAUKEE (CBS 58) -- Twin brothers Brook and Robin Lopez often joke about being adversaries, but on Wednesday, the Bucks teammates came together for a great cause. 

They read to students as part of their literacy campaign "Blocks for Books."

For each block, they donate $100 to the Next Door Foundation. So far they've raised over $15,000.

Brook is averaging 2.6 blocks per game this season, which is the best he has ever done in his career.

The money raised will go towards new books for kids in the community.
