The New York Daily News reports Montana and his family were in New York visiting colleges, and decided to stop and say hi to Cranston after one of his shows.

Montana told the paper: "He really is the nicest guy in the world. It really is true. He's not really a celebrity, he's a dude. He didn't have to help me out but it was pretty amazing."

ABC dubbed high-profile prom date requests like this one a "promposal," and a lot of guys out there are trying to step up their game to get a "yes."

As for Montana, he now has a date to his junior prom thanks to some star-studded help. He told the New York Daily News it might be tough to outdo himself for senior prom next year.
