If you've been seeing a lot of celebrities posting old photos of themselves online lately, there's a very good reason. And it's for a good cause.

Nick Kroll's #PuberMe Challenge is asking celebrities to share photos of themselves from their awkward teen years. For every celebrity who participates, Stephen Colbert will donate from his AmeriCone Dream Fund to Hurricane Maria relief efforts in Puerto Rico — and Kroll has promised to match the donations.
