... and one to ponder on ...
Very funny. As nearly all the rest had typos, I hope you did that on purpose.
I spent ages looking at the elderly sign, as I just read elderly and thought the pic must be different. Doh! They say English has redundancy built in and that's why we can read words with letters missing. I'm not sure about the other misspelt signs, perhaps a sad reflection on education today.
The rest were funny. Favourites were Danger Will Robinson, the poor dog in the litter bin and the unenviable toiletless police.
