Neil Patrick Harris and Kal Penn stopped by TRL yesterday to help get us all even more excited for this weekend's release of Harold and Kumar Escape From Guantanamo Bay — um, yay! While NPH is all about playing a caricature of himself in the Harold and Kumar movies, last night he was part of a shocking(ish?) hook up on How I Met Your Mother. It was awesome, and hey, Robin Sparkles' new video can do that to you. While HIMYM keeps getting better and better — maybe with more Brit — this weekend's movie will hopefully be as hilarious as its predecessor.
