Here is an example I see often:
Figure that one out, children.
Other examples include:
"Over my secondhand smoked body"
"Secondhand smoke two birds with one stone"
"Hard work never secondhand smoked anybody"
"Curiosity secondhand smoked the cat"
"Silent but secondhand smokely"
" 'Til secondhand smoke do us part"
"Don't secondhand smoke the messenger"
"Ding dong, the witch is secondhand smoked"
and my personal favorite, "Who secondhand smoked and made you boss?"
I want to secondhand smoke this messenger for being annoying. Also, I highly doubt that including fine print at the bottom of each board is a wise idea if your goal is to save lives. Good job.
