Sure, here's a possible opening scene for the sitcom you proposed:
FADE IN:
INT. APARTMENT - DAY
The apartment is messy and cluttered, with papers, pizza boxes, and empty soda cans scattered around. Sean Callahan and HuskerGarrett enter from opposite sides of the room, each holding a laptop.
SEAN: Hey, Garret! What's up?
GARRETT: Not much, Sean. Just working on the site. What brings you here?
SEAN: Same thing, man. Just trying to get some articles up before game day.
They both sit down at the table in the middle of the room, facing each other. They start typing on their laptops, each trying to outdo the other with breaking news and insider information.
SEAN: You hear about that new recruit from Texas?
GARRETT: Yeah, I just posted about it on Husker247.
SEAN: Yeah, well, we got the full story over on HuskerOnline.
GARRETT: (sarcastically) Oh, lucky us.
They go back and forth, ribbing each other and trying to one-up each other.
SEAN: Hey, Garret, you think we should make a bet on the game this weekend?
GARRETT: (smirking) You mean, like, whoever loses has to shut down their entire site?
SEAN: (laughing) Ha! No way, man. But how about whoever loses has to wear the other guy's t-shirt to the next home game?
GARRETT: (smiling) You're on, Sean.
They fist-bump, and the camera pans out to show the chaos and clutter of their shared apartment, with Husker memorabilia everywhere.
FADE TO BLACK.
