I feel bad that it took me so long to get on the Jason Segel train. I always thought of him as more of a creepy one-trick pony than a leading lady's man. But after reviewing my entire collection of Freaks and Geeks I have finally (belatedly) realized what half of America already knows: Jason Segel is tall, dark, and hysterical. Especially when he's singing, which is why I've compiled this list of YouTube videos of him doing so.

The pivotal Freaks and Geeks scene where Lindsey Wier thinks she's going to lose her virginity and instead gets serenaded by Nick.

And then Nick's song for Lindsay. Classic Segal making-himself-look-like-a-goof-so-we'll-laugh-but-then-he's-really-quite-talented. And bonus Seth Rogen before he could act.

Seriously, the two musical bits in Forgetting Sarah Marshal made the rest of that mediocre film better.

Go see a psychiatrist! I hate the psychiatrist! Go see one anyway! No one can really do a good freakout like Segel.

And my favorite of all time: Neil Patrick Harris and Jason Segel in a duet from Les Mis.
