Eco stuff . . . "Save the redwoods - wipe your ass with a spotted owl" It was a popular bumper sticker
I googeled: "daddy has toxic gasses" and found this place. I was trying to find a gag that aired on KPIG radio, the joke ran like an add. Dad comes home sits on the recliner and his butt starts to relax. The kids start screaming "Mommy, Mommy! Open the window Daddy's killing us!" Then a 1950's style announcer interrupts with a public health warning about how "toxic gas can kill your family" or something to that effect and the need to "ventilate and evacuate" before permanent lung damage takes place.
