Chatting with my brother in my kitchen yesterday, while making a salad:
Me: "I met a new friend on Friday. She used to program MUDs, and now runs a startup making an MMO."
Tom: "Does she have a younger sister?"
Me: "I don't think so. Actually, come to think of it, she's your type physically. She's chinese, with long straight hair, and really skinny."
Tom: "Her younger sister is?"
Me: "No! She doesn't have a younger sister!"
Tom: "Bah, so useless!" [gets up and leaves]
