I was out supporting my local labor struggle when I got this request:
9F06 7F11 7F23 7F05 7F17 8F19 7G11 8F18 7G08 7G01 7F09 9F22 2F33 9F15 2F07 2F10 7F02
So, what should I do?
Maybe you should
Play "Classical Gas"
It seems that the members of this cipher are
The way in which episodes of The Simpsons are numbered
In particular
9F06 = New Kid on the Block
7F11 = One Fish, Two Fish, Blowfish, Blue Fish
7F23 = When Flanders Failed
7F05 = Dancin' Homer
7F17 = Old Money
8F19 = Colonel Homer
7G11 = Life on the Fast Lane
8F18 = A Streetcar Named Marge
7G08 = Simpsons Roasting on an Open Fire
7G01 = Some Enchanted Evening
7F09 = Itchy and Scratchy and Marge
9F22 = Cape Feare
2F33 = Another Simpsons Clip Show
9F15 = Last Exit to Springfield
2F07 = Grampa vs. Sexual Inadequacy
2F10 = And Maggie Makes Three
7F02 = Simpson and Delilah
Reading out the first letters gives
NOW DO CLASSICAL GAS
This is
the request made by Lenny to Lisa during the episode "Last Exit to Springfield" and I think she does oblige.
