Rachel bumps into her old friend Melissa from college who she once kissed after drinking too much sangria. Monica has the seating chart for the wedding finished and Chandler is really sad that only about 10 guests are from his side. Chandler goes to see Rachel at Ralph Lauren's to choose a tux and picks the tux that Pierce Brosnan wore once and sent back. Chandler thinks he is the coolest until he finds out that Ross picked the tux worn by Val Kilmer in Batman. Phoebe doesn't believe Rachel that she made out with Melissa so she goes to dinner with them to ask Melissa about it. But unfortunately for Rachel, Melissa can't remember anything. To prove to Phoebe that she is wild Rachel kisses Melissa again and Melissa admits being in love with Rachel and remembering the kiss all the time. It turns out that Ross' tux was worn by Val Kilmer but not in Batman. Chandler finds a new tux - which was worn by Diane Keaton.
