The insanely popular show 30 Rock will undoubtedly be twice as funny and twice as good tonight when it goes LIVE!

Creator Tina Fey, who stars in the show, warns potential viewers:

“People shouldn’t watch if they’ve taken any kind of heavy medication,”

There will be two live shows — one for each coast — and Tina is fearful since “So much can go wrong,”.

Star Alec Baldwin jokes that Tracy Morgan (who plays Tracy Jordan) is the only thing they’re really worried about:

“The only fear factor is Tracy,”

But with Saturday Night Live under his belt, Tracy assures that he won’t trip:

“Seven years of SNL have prepared me for this,”

“I read the script and I know my lines … I’m going to disappoint a lot of people.”

There haven’t been any major spoilers leaked (duh, since no one has seen a preview) but rumor has it that Liz Lemon will be having a 40th birthday celebration and two of her former love interests, Carol (Matt Damon) and Dr. Drew Baird (Mad Men‘s Jon Hamm), will be there to celebrate.

Matt Damon? Might have to tune in to NBC at 8:30 ET.
