On Thursday, a 17-year-old from California named Stefan Montana waited for BRYAN CRANSTON outside his Broadway show in New York, and asked him to help ask a girl to PROM. Ya gotta hand it to this kid for having the persistence to wait with no guarantee that Hiesenberg would do it.   

He had an iPad, and asked Walter White to record a video message where he said the girl should, quote, "tread lightly" if she doesn't say yes.  Which was a reference to something Walt said to Hank in season five of "Breaking Bad".   Later, Stefon revealed on Twitter that the girl said YES.

Pretty cool of Walter White to do this!
