I've seen many unique bathroom signs. On our travels when you don't speak the language, sometime it's a little confusing. When we were in Germany with Margaret and Dave, Dave went to the bathroom. When he returned he asked Cec (who speaks and reads German) if he went in the right bathroom. He didn't and we had the best laugh. Thankfully no lady came in when he was there!
I saw these online, but I think I will start taking picture of unique bathroom signs from now on:
