Thanks to Judd Apatow's films 'The 40 Year Old Virgin' and 'Knocked Up,' Seth Rogen quickly became a face we know and love. In today's Way Back When, we show you Rogen before he was making you laugh on a regular basis.

'Freaks and Geeks'

If you've been following Way Back When, then you know we have a thing for 'Freaks and Geeks' around here -- the short-lived show from Paul Feig followed two groups of friends in high school, with Seth Rogen playing Ken Miller, a stoner of the Freaks group. In the clip below, watch Rogen alongside James Franco, Jason Segel, Busy Phillips and Linda Cardellini, as the group tries to convince good girl Lindsay that they should have a kegger at her house while her parents are out of town:

'Donnie Darko'

Rogen didn't always play a lovable goofball -- in the 2001 film 'Donnie Darko,' Rogen plays Ricky Danforth, a total jerk and bully who picks on the titular character (played by Jake Gyllenhaal) and his girlfriend (Jena Malone). The video below features a compilation of his scenes, including one where he creepily hits on Malone by uttering the eloquent phrase, "I like your boobs."

'Dawson's Creek'

In 2003, Rogen reunited with 'Freaks and Geeks' co-star Busy Phillips for the 'Dawson's Creek' episode titled "Rock Bottom," in which Audrey (Phillips) hooks up with 21-year-old Bob (Rogen), a stoner (obviously) whom she sleeps with and uses to further her descent into addiction. Joey convinces her to go to rehab, but Audrey demands that she's allowed to take Bob with her, and they all go on a wacky cross-country road trip -- because apparently there are no rehab facilities near the ol' Creek.


As with Jason Segel, Seth Rogen also graduated up from 'Freaks and Geeks' to 'Undeclared,' another short-lived Paul Feig series, this time following the lives of undecided college freshmen. You can see Rogen as his character Ron Garner (and yes, he was a stoner here, too -- art imitating life) alongside Jay Baruchel, Charlie Hunnam and Timm Sharp in this scene, where the guys play a video game and ponder which lady friend of theirs has the best caboose:

'Anchorman: The Legend of Ron Burgundy'

Rogen had a very, very small part in the 2004 insta-classic Will Ferrell and Adam McKay comedy 'Anchorman: The Legend of Ron Burgundy' (and we cannot wait for the sequel!). Rogen played the part of "Eager Cameraman," and while we can't find any video clips because the part is so very minimal, enjoy this cute photo of Rogen behind a camera:
