This one time In my street I saw a wifi saying "give back our flamingos" and another saying "**** your flamingos"
"Get your own wifi" "Lazy bums steal wifi" "FBI truck" "Hey no free wifi" "Wifi stealer" I've seen even more funny wifi names only because I like walking so I usually walk around my neighborhood and I tend to see if I could connect to a wifi whenever I take a break, these are the only ones I remember right now
