overheard at the gym

Spin Teacher: "So bring your bike next week because this class is going to be outside."
Clueless Student who is wicked annoying because she does not ever stop talking about herself: "I gotta go buy a bike still. I saw a nice one at the store for only $500."
Teacher: "There are some good ones on Craig's list too."
Student: "Who's Craig?"
Teacher: "You've never heard of Craig's list?"
Student: "No, is this like someone you know?"
