Ep 4. The Stinson Missile Crisis

Marshall has done everything he can to make sure that his dream job offer isn't rescinded; that includes keeping his old boss happy enough to pay a visit and pretend to be his current employer. Meanwhile, Robin has been offered a new job opening that would take her back to her birth country of Canada. The potential move worries Barney, who fears that he will lose his wingman. To make matters worse, Ted goes on a mission to bring back the running joke of "the Blitz" by finding the last remaining members of the gang he's a part of.
