This was back in maybe the mid 80's, I was working in dispatch and about 5AM while monitoring ATC I heard an Airborne Express YS-11 climbing out of Wilmington (ILN) on the freq. This was in the dead of winter and mod to sev icing was all over the ohio valley and the female controller was asking for pireps. I heard her ask Airborne "ABX 221 are you on top?" and the pilot on the radio comes back with " Naw..We are in and out" Everyone in the dispatch office heard that and busted out laughing. To this day I don't think either one of them realized what they had said.
