Throwing a complete game shutout is probably a very tiring ordeal, but even after that and celebrating with his teammates and family, Jake Arrieta still found some time very late at night to jump on Twitter to answer a fan question with a wonderful response.

One Pirates fan jokingly wondered if the Cubs ace’s constant fidgeting might mean he was flouting the rules in some way, and Arrieta was happy to explain himself at 4:30 a.m.
