God did it on purpose so that we may love you men instead of laughing at you.

The line reads as a wry, gendered epigram: men’s shortcomings (or the comic spectacle they can make of themselves) are framed as so obvious that, without some counterweight, women would respond with ridicule rather than affection. By attributing that counterweight to divine intention—“God did it on purpose”—the speaker turns a potentially biting observation into a playful justification for love, implying that love is not always earned by merit but enabled by a built-in human (or social) design. In Mrs. Patrick Campbell’s idiom, it also functions as a stage-ready quip: a flirtatious, slightly sardonic remark that flatters and needles at once.
