With the fourth season premiere coming around the corner, CBS have released a promotional video for "How I Met Your Mother". Cracking the jokes from Neil Patrick Harris' character Barney who stuns Lily (Alyson Hannigan), the clip is relatively short, running under 12 seconds.
The 4.01 episode which will be called "Do I Know You?", recurring role Stella (Sarah Chalke) has to give Ted (Josh Radnor) an answer regarding his proposal. At the same time Barney realizes that he is in love with Robin (Cobie Smulders) and wants to say something about it.
Returning for the new series after the highly-acclaimed third season where Britney Spears make occasional cameo as Abby, "How I Met Your Mother" will air its new season starting from Monday, September 22.
