- The two are raising money for Puerto Rico with a challenge to celebrities
- Stars respond with photos of themselves in that awkward adolescent stage
Kroll was on Colbert's late-night show Wednesday to promote "Big Mouth," his new animated series on Netflix about the challenges of puberty.
Kroll challenged fellow celebrities to post awkward photos of themselves during adolescence using the hashtag #PuberMe.
Colbert jumped on the idea and said that if stars added #PuertoRicoRelief to those postings he would ensure proceeds from the sale of his Ben & Jerry's ice cream flavor, Americone Dream, would be donated to help people on the hurricane-ravaged island.
On Thursday night, Colbert announced that for every posting the Americone Dream fund would donate $1,000 to OneAmericaAppeal.org
"And again, I get to determine who's a celebrity," Colbert joked.
Several stars took the challenge, including Sarah Silverman, Kevin Smith, America Ferrera, Emmy Rossum, Lena Dunham and Conan O'Brien.
Of course, Kroll and Colbert also got in on the action.
The challenge is just the latest in celebrity efforts to raise funding and awareness about Puerto Rico, the US commonwealth devastated last week by Hurricane Maria
