Nick Kroll's new show, Big Mouth on Netflix, is all about the agony and the ecstasy of puberty, a process that celebrities surprisingly had to endure.

Kroll challenged his fellow celebrities to share photos of their pubescent days, kicking off the #PuberMe campaign.

For every celebrity who put up a puberty picture, Colbert vowed to donate money from his Americone Dream Ice Cream Fund to Puerto Rico hurricane relief, which Kroll himself will match.

Nick Kroll asked me to post a pic of my awkward stage, but I never had one. So here's me lookin' cool as hell! #PuberMe #PuertoRicoRelief pic.twitter.com/UC9a7XtjZa
