The clip aired on Good Morning America Friday and found the actors putting their survival skills to the test as they prepared to spend a night in the wilderness, nude.
"You're supposed to be a hot Australian-like survivalist!" Franco tells Rogen upon realizing he'll be his mate.
"Do you know anything about surviving out here?" Rogen answers right before Franco gets closer and gives him a naked hug.
In Naked and Afraid, a pair of contestants, who are strangers, are sent into the wilderness each week where they must survive for 21 days "with nothing but one personal item each and the knowledge that the only prize is their pride and sense of accomplishment," according to the show's website.
Rogen reveals in the clip he brought toilet paper, while Franco chose a pair of sunglasses.
Franco teased his and Rogen's involvement in the reality series last month when he shared several pictures from the episode on Instagram.
