Firehouse Subs®, the firefighter-founded hot sub chain, is cranking up the heat with an exciting new partnership with Hot Ones™, the legendary hot wing celebrity interview series. This collab means guests nationwide can test their heat tolerance with two flavor-packed new subs: the Spicy Dill Hook & Ladder (HOT!) and the Zesty Garlic Hook & Ladder (mild heat).

Priyanka Chopra Jonas and Jimmy Fallon put their taste buds in real jeopardy for a hilariously spicy segment on Thursday's Tonight Show. Taking a cue from the hit YouTube interview series "Hot Ones," Priyanka and Jimmy were joined by the web show's host, Sean Evans, who grilled the pair as they ate progressively hotter and hotter chicken wings, amazingly, of their own volition. As Jimmy introduced the segment, Priyanka said she already know all about it, seeing as how Nick Jonas -- and his brothers, Joe and Kevin -- sat down with Sean for their own episode of "Hot Ones"back in May. While the segment was significantly shorter than a full episode of "Hot Ones," both Jimmy and Priyanka began to totally melt down by the time they got to the final wing, with "The Last Dab" hot sauce.
