Motherhood Quote by Phyllis Diller

"My mother-in-law had a pain beneath her left breast. Turned out to be a trick knee"

About this Quote

It lands like a pratfall dressed up as a medical emergency: you’re guided toward dread, then yanked into absurdity. Phyllis Diller weaponizes the familiar rhythm of domestic concern - the worried report, the ominous anatomical detail - only to detonate it with a punchline that’s pure misdirection. A “pain beneath her left breast” cues heart attack panic; “trick knee” is gloriously banal, even vaudevillian. The laugh isn’t just at the non sequitur, it’s at how easily our brains sprint toward catastrophe when a body is involved.

The real target, though, isn’t medicine. It’s the mother-in-law, that midcentury comedy piñata, and the unspoken family tension she represents. Diller’s persona thrived on turning suburban grievances into spectacle, and the mother-in-law joke is a socially acceptable way to admit: this person makes me anxious, and I’m not allowed to say it plainly. By fusing “beneath her left breast” (intimate, taboo-adjacent) with “knee” (safely ridiculous), she also sidesteps propriety while still flirting with it. The body becomes a battleground for decorum.

Context matters: Diller broke through in an era when women comics were expected to be “harmless” while still being sharp. Her solution was baroque silliness with a razor inside. The line reads like a throwaway, but it’s a tight little machine: fear, release, and a wink that domestic life is its own kind of emergency room.
