The Twizzler Challenge is a new dare aimed at raising awareness for autism.
Girls stars Lena Dunham and Allison Williams showed they'll do anything for the good cause by taking part in the charity kissing challenge for all to see.
Lena, 28, shared the experience on Wednesday via a brief video clip, which began with her sitting on a couch with Allsion, 26, and clutching a cherry-flavoured Twizzler.

Participants are required to place one end of the candy in their mouth and chew until their lips touch, and Lena and Allison didn't hesitate.
'We are here to take the Twizzler Challenge for autism in honor of our dear friend Natasha,' Lena said, and Allison added: 'New York Collaborates for Autism, we love you.'
They quickly ate up their ends of the candy and locked lips before declaring it a success.
