Ready ... set ... weep. The "How I Met Your Mother" series finale airs on March 31 and CBS shared a 20-second promo for the hour-long special at the end of the show's penultimate episode. "Let them surprise you one last time," the network said.
Some fans have been theorizing for years that the Mother, played by Cristin Milioti, will be dead in the last episode and that the entire series led up to that one idea. In "Vesuvius," the show seemed to prove that theory, but Milioti has called that idea "insane."
Though it's uncertain how the show will end, it's clear that the finale will make longtime viewers endure all the feels when Ted actually meets the Mother.
