Kevin (How I Met Your Mother)
Although Kevin (Kal Penn) and Robin (Cobie Smulders) need to break up so that she can get back together with Barney (Neil Patrick Harris), we'd like to see him stick around a while longer. After all, if there’s one thing we’ve learned from HIMYM, it’s that exes can remain friends. Plus, the gang needs someone to call them out on their craziness, which Kevin often does. It doesn’t usually have much effect, but we love the juxtaposition of the sane and, well, less sane.
