If there's one thing that long-time fans of HIMYM know, it's that the writers love a very detailed inside joke. Monday's episode will feature a trailer starring Jason Lewis, Chris Kattan, and Malin Ackerman that hits too close to home.
If it's eerily similar to the storyline of Ted and Stella, that's because it is their story. Ted will apparently bring a date (played by Judy Greer) to the movies and will be horrified at Chris Kattan's potrayal of "Jed Mosley."
There's also a website for the faux-movie that you can explore here.
