We had DD1 on April Fool's day. When DH announced, "It's a girl!" He told my mother & MIL that we decided to smoosh their names together and we named her JoLeen (My mom is Joanne my MIL is Kathleen). They both stared at him in disbelief and then he said, "April Fools". They weren't sure of what they were joked on- the girl or the name or both!
