They may have developed a rivalry that's resulted in them being enemies in the ring, but "Arrow's" Stephen Amell and WWE wrestler Stardust put aside their differences last weekend for the benefit of a cause they both believe in. The pair met, not in the confines of the squared circle, but at Toronto-based children's hospice Emily's House, where they co-presented a check for $297,557 to the facility.

The funds were raised through sales of a special t-shirt commemorating the duo's first-ever wrestling confrontation at last August's SummerSlam pay-per-view event. The shirt, produced in conjunction with WWE, celebrates Amell's rivalry with WWE Superstar ("Superstar" is WWE's official terminology for its pro wrestlers) Stardust and is based on an image designed by artist Danny Haas.

[T]today... Stardust and I presented Emily's House in Toronto with a check for $297,557 and helped open the Dream Space Playroom in memory of Oliver "Odd Sock Ollie" Muirhead," Amell posted on his Facebook page. "Can't really put into words what a special morning this was. The people who work and volunteer and Emily's House are actual real life superheroes. The Muirhead family should know that their Son left a wonderful impression. And forgive the break in character for a moment, but Cody Rhodes is one of the most selfless, genuine human beings I've ever had the pleasure of meeting. What a day."
