Odin, who according to his mom has Asperger syndrome, expected to bowl the night away with friends Friday night at an alley in the Canadian city of Peterborough, about 70 miles northeast of Toronto. But when no one responded to his mom's invitation, an exasperated Camus took to Facebook.

"Some of you have seen me post about my son, Odin," Camus wrote in a Facebook post, according to a screen shot posted by Peterborough news and entertainment company PTBO. "His struggles with bullying, his difficulties with Aspergers. Well, today is his 13th birthday. And, unfortunately, not one kid rsvp'd to his birthday 'hang out' invite. :-( I'm really struggling with finding a way to make today awesome for him, when it will just be us celebrating."

Camus did what she could on her own to make the occasion special, planning a "balloon avalanche" for the morning of his birthday, as well as house decorations, dinner at his favorite restaurant, presents and cheesecake. But perhaps she didn't realize the scope of the celebration was about to change dramatically when she asked Facebook users to to wish Odin a happy birthday on "his schmancy new cell phone."

That's when PTBO posted an article about Odin's situation, and encouraged readers to show up at nearby Lakeview Bowl — the destination for Odin's birthday party —to wish the boy a happy birthday on his first day as a teenager

But even before Odin showed up at the venue, he received thousands of social-media birthday wishes — including some from Hollywood stars, prominent politicians and professional athletes who might not otherwise wish strangers a happy birthday on a daily basis.

Players, mascots and staff of many of Ontario's sports teams were among the first to get in on the act, using the hashtag #OdinBirthday
