"Susan, how do you know you love me?" asked Tom.
"I know I love you because you are always there for me when I need you. I love everything about you. I love to take care of you when you're sick. I love to watch you when you sleep. I know I love you because I want to marry you and have a baby with you and spend the rest of my life with you." replied Susan.
"Is that so?" said Tom.
"Yes. How do you know you love me?" asked Susan.
"Because you give a good blow job." replied Tom.
