Strong weakness

Figure of speech. Lenehan's not very funny pun provokes an equally feeble catchphrase from one of his listeners: "See the wheeze? Rows of cast steel. Gee! / He poked Mr O'Madden Burke mildly in the spleen. Mr O'Madden Burke fell back with grace on his umbrella, feigning a gasp. / — Help! he sighed. I feel a strong weakness." The saying is an instance of the familiar device of oxymoron, a self-contradictory pairing of words.
