brake warnings are dead (or broken)

I saw a Staples truck that said "I brake for empty staplers."

This is officially the truck that cried wolf. All other brake warnings are now meaningless.

What was the original brake warning? Something like "I brake for children," I imagine. As well you should. "I brake for deer" -- well, thanks for letting me know. "I brake for unicorns" -- cute. Unicorns aren't real, but they are sort of similar to deer, so ha ha funny okay.

Empty staplers do not cross roads. Not even in jokes. They cross roads less often than chickens, which, truly, do not cross roads very often themselves. Chickens lack motivation.

Staples is the straw that broke the camel's back of the brake warning. Not that anyone is going to brake for even a broken-backed camel anymore, what with Staples crying wolf with the sub-chicken camel-crushing stapler brake warning.
