30 Rock is gearing up for its second live episode Thursday, and Tina Fey just hopes it goes better than that time she threw up during Saturday Night Live.
"I had five minutes to go before Weekend Update [and] I barfed in the bathroom. I was just getting the flu or something. I was like, 'Oh, no!'" Fey tells TVGuide.com. "I made it back and didn't barf on the air, but I was laid up after that."
Community's Donald Glover to visit 30 Rock's live episode... as Tracy Jordan?
Luckily, her 30 Rock co-stars Jack McBrayer, Jane Krakowski and Tracy Morgan haven't endured such agony.
Check out the interview below to find out their worst live TV blunders, what to expect from Thursday's episode — which will feature many flashbacks to old TGS shows — and exactly how many celebrity cameos you ought to keep an eye out for.
30 Rock airs Thursdays at 8:30/7:30c on NBC. The cast will perform a live East Coast and West Coast show.
