A blonde goes in for a job interview. The hiring manager asked, "How old are you?" She begins counting her fingers and toes and answers I'm 20.
He then asks her, "How tall are you?" She begins measuring herself from the feet up and answers, "I'm 5'6."
He then asks, "What is your name?" She closes her eyes and starts silently singing to herself and then answers, "My name is Kathy." Puzzled the hiring manager asks her, "I understand you counting to get your age, and measuring to get your height, but what did you do to make you remember your name?" She answers, "I was singing 'Happy birthday to you. Happy birthday to you. Happy birthday dear Kathy!"
