Illustration for riddle: What calls for help, when written in capital letters, is the same forwards, backwards and upside dow

Common Wrong Answers

WOW

While 'WOW' is a palindrome and looks the same forwards and backwards, it does not represent a call for help, and it does not appear the same upside down.

MOM

'MOM' is also a palindrome, but it does not convey a call for help like 'SOS' does, and it doesn't look the same upside down.

DAD

'DAD' is another palindrome, but like the others, it lacks the meaning of a distress signal and does not maintain its form when turned upside down.
