Do all girls have a low sense of humour??

So I was trapped among my sister's friends for an hour and I realised they laugh at the most unfunniest and non humourous things in the world and I was having a hard time faking my laughter in front of them. Also I found out how easy it is to make them laugh , just say any random thing in a funny tone and they all burst out laughing and I have been testing this thing on many girls and it literally works on everyone. I wonder whether us boys have too advanced and dark humour or girls have a trash humour
