Chris Pratt, the newly-named Harvard Hasty Pudding 2015 Man of the Year, has once again proven why he's more than deserving of the honor. 

The 35-year-old "Parks and Recreation" actor paid a visit this week to the Children's Hospital of Orange County, spending an entire day bonding with sick kids and handing out toys. In one touching moment he shared online, Pratt celebrated the good news that his new friend Emma was now cancer-free.

"After a long battle with childhood leukemia, Emma is going home cancer free!!!" he wrote on Facebook. "Atta girl! You kicked cancer's butt!!! Thank you to Children's Hospital Orange County for setting up an amazing visit and to Emma for my wonderful painting."

Pratt, who earlier visited the Los Angeles Children's Hospital in August, revealed that he stole his Star Lord costume from "Guardians of the Galaxy" well before it came out — just in case it became a mega-hit and he could use it to help bring smiles to children. 

"If it was a big enough movie to where it would mean something to a kid who’s sick in the hospital for Peter Quill or Star-Lord to come visit them, I’ll do that," he said. "I think that’s awesome, man. That would give me real meaning for this movie, you know?"
