A blonde goes in to apply for a job and she fills out an application. She takes it up to the man and he says you forgot three blanks. He asks how old are you, so she counts on her fingers and finally reaches 22, okay then how tall are you so she tries to measure herself she says 5′2, okay then what is your name, she nodes her head back and forth for a few seconds and says Jennifer. He says okay I get how you got your age and you height, but how did you get your name by nodding your head back and forth, she says I was singing “Happy birthday to you, Happy birthday to you, Happy Birthday dear Jennifer.
