I had never seen Failblog before, rather amusing!

Don't know how to set the code to show the picture.

I ran across this one at Toys-R-Us today. I think it qualifies for this thread.

Heh, which reminds me of this, seen over a hospital bed:

Attachment 1574

On that one I envision it originally saying "Psychological needs" and someone later thinking that sounded to clinical and changing it without paying attention.

Doing content reviews right now for a couple projects and I'm freshly reminded at how many people think you can just go through changing individual words without ever looking at the entirety again.

I guess the person who changed #3 from "Pee" to "Personal Needs" just got lucky.

You could just cross out 1 to 4 and replace with "Because blood in your P is a bad thing."
