The tale will come to an end next year when the sitcom wraps up its ninth and final season.
To promote the fresh run of episodes, CBS played a video featuring "HIMYM" cast members Lyndsy Fonseca and David Henrie Saturday for fans at Comic-Con.
The expletive-ridden clip showed the now-adult brother and sister rebelling because, they said, they have given up their own lives for eight years to sit on a couch and listen to their father detail their family's origins story.
Executive producer Craig Thomas said in a statement the video is intended to explain what the kids do off-screen when the story is unfolding elsewhere.
"This video took eight years to make," Thomas said. "But as we start to answer all of the remaining mysteries of 'How I Met Your Mother,' we just knew that this was one question that we had to answer."
