Monica is reluctant to introduce her new boyfriend,Alan, to her friends because they have mocked all of her previous boyfriends. To her surprise, after meeting Alan, they tell her that they love him. However, she later realizes that she does not feel a spark between Alan and herself and asks her friends if they think that he can sometimes be a little "too Alan". Joey has a part in a play where he has to smoke, and practices smoking with Chandler, who resumes his smoking habit, much to the group's irritation.
Phoebe becomes very agitated with her bank when they accidentally put an extra $500 in her bank account. Not able to use the money due to guilt, Phoebe informs the bank of this error. She receives a football phone for the inconvenience. However, instead of removing the $500 from her account, they add another $500 to it. She gives the money and the phone away to Lizzy, a homeless acquaintance. Lizzy buys her a can of soda out of gratitude. When Phoebe opens it, she sees a thumb, so she receives compensation from the soda company of $7,000. The episode ends with Phoebe giving the $7,000 to Chandler, if he promises to never smoke again.
