Jimmy Fallon had Mr. Ben and Mr. Jerry on his show last night to unveil his second Ben and Jerry's flavor. The Tonight Dough includes chocolate and caramel ice cream, chocolate chip cookie dough, peanut butter cookie dough, and a chocolate cookie swirl. This isn't Jimmy first time at the ice cream rodeo-- his last flavor, Late Night Snack did well. But he called The Tonight Dough a whole new level.
