(NEW YORK) -- Move over, ice water buckets: a new viral campaign has male celebrities grabbing their packages to raise awareness for testicular cancer. Both to get the word out about the disease -- and possibly remedy any remedial "shrinkage" from all those ALS Ice Bucket challenges -- famous folks like Hugh Jackman and Ricky Gervais were among the first stars to take part in #FeelingNuts.
The X-Men series star and apparently some gym buddies posed on his Instagram account, with Jackman writing, in part, "...#feelingnuts raising awareness for testicular cancer. Nominating @ActuallyNPH [Neil Patrick Harris] @michaelstrahan @rickygervais." Jackman also posted a dramatic video, captioning it with, "#feelingnuts in slomo! Raising awareness for testicular cancer. #youknowwhoyouare."
Gervais was game, with a picture that featured him flipping off the camera, punk rock style; he in turn nominated William Shatner and Will Arnett, saying to the latter, "You might need bigger hands. Am I right?" Arnett posted his own picture back to The Office co-creator, saying, "no..all good."
