I’m a big fan of stick figure signs, especially when the stick figures have a personality. While never having been electrocuted — just minor tingling when I tried to unplug my hair dryer with a wet hand — I’m guessing the second sign is a more accurate depiction of what it’s like to touch a high voltage power box.
Sign One (sorry about the blurriness)
This stick figure could easily be on a caution sign as someone climbing, dancing, falling off a swing etc.
Sign Two
Now here is someone that accurately reflects (I think) being electrocuted. Plus, how evil high voltage can be!

The first pic appears to be an electric powered mailbox. That is scary.
I wasn’t sure exactly what it was, but yes, scary and clearly packs a mean punch!! Thanks for the comment.
So where are you safe. Haha.
Yes, it’s a bit disconcerting. I was just talking to someone today about Australian warning signs (like beware of snakes on the beach) and I said, “When Australians warn you about something, you better listen.” Since you guys seem to take things more in stride, and are more realistic. 🙂
Terrifying!! Certainly leaves nothing to doubt!
The second sign is near my parents’ house and it freaks me out every time I visit. I practically put police tape around it when I’m out walking with my kids. Thanks for the comment, my friend! 🙂
Very shocking !!!!!!!!!!!!!!!!!!!!!!!!!!
