Not regional and not my IOE but I'll always remember the first leg of a peach-fuzz engineer shortly after I got a window seat. Eyes the size of saucers, his check engineer dozing in the corner after we reached cruise, he was just starting to settle down when the senior came in to take drink orders. When she was finished with the Captain and I, she turned to this cherub engineer and, in her deepest Texas twang said, "I'll come back and breast feed you, Junior!"
