#FeelingNuts Viral Challenge Gathers Steam After Hugh Jackman Takes Part

An online “crotch grab challenge” started by a testicular cancer awareness group in the United Kingdom received a viral boost Wednesday from Hugh Jackman, who tweeted a picture of himself taking part.

The challenge requires participants to hold their crotch and then share a photo of themselves online. It appears to be one of the first health-minded social media campaigns to take off after the colossally successful ALS Ice Bucket Challenge.

The Check One Two group, founded in 2012, has gradually gained traction online since launching the “crotch grab challenge” in August, with Jackman’s tweet likely to set off a new round of virality.

The X-Men star tweeted a photo Wednesday morning of himself and three other men holding their private parts and lifting their arms in greeting toward the camera in what looks to be a gym.

Hugh Jackman nominated Neil Patrick Harris, Michael Strahan and Ricky Gervais, who shortly afterward tweeted a photo of himself completing the challenge in August.

Will Arnett also participated at the end of August.

The ALS Ice Bucket Challenge has raised more than $100 million and may have ushered in a new era of online fundraising and social awareness. Unlike the Ice Bucket Challenge, however, Check One Two’s crotch grab challenge doesn’t ask participants to contribute money.

Check One Two says on its website that its aims are “1. Spread awareness far and wide of #feelingnuts in funny, ball grabbing and pant dropping ways” and “2. Educate men and the women in their lives about how to check their nuts for testicular cancer.”
