At one point during the live presentation of '30 Rock' this week (at least with the East Coast version), Jenna Maroney boasted “I was on stage in ‘Pippin’ with Irene Ryan when she died, and I kept going.”
Irene Ryan, better known to Toobworld watchers as Granny on 'The Beverly Hillbillies', died in 1973 of a brain tumor at the age of 70 while she was playing Pippin's grandmother in the Broadway musical. If Jenna is the same age as Jane Krakowski (the actress who plays her and who has her own Toobworld presence in those Tropicana 50 orange juice commercials), then she's 42 years old. And that would mean she was five years old when she appeared on the Broadway stage with Irene Ryan in "Pippin".
This is not a problem. Really.
The "Pippin" seen on Broadway in the real world only had one small child, the son of the woman Pippin loved at the end of the show. But with its televersion, there may have been other children integrated into the show, or at least just one other one - a little five year old girl.
It could have happened. And like with reasonable doubt, that's all you need.
Of course, it could have all been a delusion due to Jack's abstinence from alcohol......
