Neil Patrick Harris To Guest Voice-Star As ‘Prince Gumball’ On Cartoon Network’s Adventure Time!

We love you, NPH!

Check out the preview (above) of an upcoming episode of Cartoon Network’s Adventure Time, which features Neil Patrick Harris as the voice of Prince Gumball!

Looks like it should be a silly, fun time.

Oh, and is it just us, or does it look like Neil is gonna be HIGHlarious in the new Harold & Kumar flick as well???
