Valve has just released the first TV ad spot for Portal 2. In case you live in a region where this won't air, or simply wish to view this before it hits your TV set, take a gander below. I promise you won't be disappointed (aside from being disappointed that Portal 2 isn't released yet).
Portal 2 is slated for release on April 19th.
