At Central Perk, the gang is there. Ross shows baby pictures to the group.
Rachel grabs the pictures & just wants to kiss him all over. Ross is basically drooling over her at this point. Chandler makes a "pfft" noise at Ross' fawning over Rachel.
Chandler walks over to Joey, who is looking at his check. Joey is in need of some money & asks to borrow some from Chandler. Chandler wants to know where his money is going. Joey tells him he is participating in a research program at NYU Med School. Ross overhears and wants to know what kind of research. Joey tells the group it's a fertility study. The group makes fun of his "contributions." But he gets $700 in 2 weeks for his time. Monica & Phoebe are preparing for a barbecue for Rachel's birthday. Joey & Chandler enter the apartment with charcoal.
Phoebe asks Joey how is his relationship with Melanie going. Joey says it's tough because she wants to have sex but he can't for another week, until he is finished with the program.
