"Jack McBrayer has teased that anything could happen on tonight&amp;#039;s (April 26) 30 Rock live episode. The Kenneth Parcell actor and Jane Krakowski shared their fears about acting on live television in an interview with TV Guide.   &amp;quot;All of us [are] worried about forgetting our lines mid-sentence, but then there&amp;#039;s also other things like if you accidentally swear,&amp;quot; McBrayer said, adding: &amp;quot;Or, [if you] pass gas!&amp;quot; &amp;quot;Or pass out, which could possibly happen to me,&amp;quot; retorted McBrayer&amp;#039;s co-star Krakowski.  30 Rock co-creator Tina Fey recalled her own blunder while preparing for Saturday Night Live years ago. &amp;quot;I had five minutes to go before &amp;#039;Weekend Update&amp;#039; [and] I barfed in the bathroom,&amp;quot; Fey recalled. &amp;quot;I was just getting the flu or something. I was like, &amp;#039;Oh, no!&amp;#039; &amp;quot;I made it back and didn&amp;#039;t barf on the air, but I was laid up after that.&amp;quot; Fey has promised surprises for tonight&amp;#039;s show, including possible cameos from &amp;quot;friends of 30 Rock&amp;quot;. The sitcom&amp;#039;s October 2010 live episode boasted appearances from Matt Damon, Jon Hamm, Julia Louis-Dreyfus and Bill Hader. 30 Rock airs its live episode at 8.30pm on NBC on the East Coast. The cast will perform the show again three hours later for the West Coast. Watch a promo for 30 Rock&amp;#039;s live show below:  "^^<http://www.w3.org/2001/XMLSchema#string>
