Jess is always playfully picking on Jack, when she writes their segments she'll put sticky notes about things 'not to say on air' which Jack just ignores and does anyways. One example is in Operation C.O.U.C.H. when he states, "The Common Cold could snot handle Sector Q's 2x4 techonology," Jess had written "Do NOT make any snot jokes about how the Cold could not handle Q's tech." It was written in such a way that the second not was below snot, which is how Jack got the idea.
