Brave Liam Fitzgerald has Down's Syndrome but at only eight he has beat cancer and now he is an online hit.
Little Liam got to fist bump all the players in his favourite ice hockey team The Boston Bruins.
And now the video has gone after viral clocking up over 2 million views making him an internet sensation.
When he was just four-years-old Liam was diagnosed with Acute Lymphoblastic Leukemia, cancer of the white blood cells.
But within three years he bounced back to beat the illness and his message here is clear: "I kicked cancer's butt!"
Speaking to Boston.com Liam's mother Christine said: "It amazes me given what he's gone through in his eight years of living. He just goes on.
"People tell us he's so cute, and this and that. He was given to us to raise and given to the world to love.
"He brings joy to people. His smile, his personality. He's such a joyful person. He's taught us a lot about life."
