CBS TV network releases another brief promo video ad called "Mother of all Mondays" for the upcoming final season of "How I Met Your Mother" to make the fans more excited with the premiere episodes "The Locket/Coming Back."

The ad shows character Lily Aldrin as the first person to have an encounter with "The Mother" but it does not appear to be a pleasant one.

More details are slowly seeping out about "The Mother" character that actress Cristin Milioti portrays as "How I Met Mother" Season 9 premiere approaches.

She made a brief but memorable appearance at the Season 8 finale with her "Hi, One ticket to Farhampton please" dialogue and now, "The Mother" seems to have met Lily Aldrin first in a promo ad though they end up fighting over something.

The brief promo video is already a foretaste to the excited viewers showing "The Mother" being a feisty one that can match up to Lily's spunky attitude. The reason behind the conflict between Lily and the future Mrs Ted Mosby will be revealed when Season 9 returns.

The other recently released CBS promo trailer offers the HIMYM fans a sneak peek of what to expect in the upcoming final season like the slap bet.

A couple of dialogues from the cast members were shown in the video clip like Marshall declaring "I'm going to ruin this wedding" and Barney harshly telling Ted that "Robin's marrying me, not you."

"How I Met Your Mother" Season 9 is now expected to focus on how Ted Mosby will meet, fall in love and marry the right girl aside from the wedding weekend of Barney and Robin. The final season will be narrated within Robin and Barney's wedding weekend where the lives of the HIMYM gang begins to change.

Other faces in Season 9 will appear as well in the hit CBS TV sitcom and it includes confirmed guest stars Anna Camp, Roger Bart, Wayne Brady, Sherri Shepherd and John Lithgow. The "How I Met Your Mother" gang will reunite for the last time in the concluding season when it premieres on September 23 at 8 p.m. ET on the CBS TV network.
