Major McGlusky: Look here, O'Leary, we *must* get this straight.
Jasper O'Leary: All right. Once and for all, I cannot accept responsibility for the deathbed ramblings of an aged lunatic.
Major McGlusky: Lunatic? General? Sanest man I ever met!
Jasper O'Leary: An 82 year-old man with one eye who tries to jump a 10-foot wall on a 20 year-old horse - - "sane"?
Major McGlusky: Ooh, well, he was mad to try it, but he was *not* insane!
Jasper O'Leary: I'm sorry, I've not lived long enough in Ireland to appreciate the logic of that remark.
