Megan Bailey appeared in The One With The Cheap Wedding Dress. She is a bride-to-be who meets Monica in a wedding dress store. She tells Monica how beautiful she looks and they get to talking. Monica tells her about a discount store, Kleinman's, in Brooklyn that is having a 50% off sale soon. While Monica is at Kleinman's looking for her wedding dress (with the assistance of Rachel and Phoebe), she sees Megan again. Only this time she is clutching she same wedding dress that Monica planned on buying. After wrestling her to the ground, Monica manages to escape with the dress.
Later, Megan calls Monica and tells her that she has booked the Swing Kings on the day of Chandler and Monica's wedding and that Monica cannot have them unless she gives her the dress.
Eventually Monica obliges (after trying to dissuade Chandler from wanting the Swing Kings, but failing) and gives Megan the dress (however Monica told Chandler he could maybe rip the dress a little bit).
- Megan tells Monica that her wedding date is July 25.
- Megan's fiance wants the heavy metal band, Carcass, to play at their wedding. When Phoebe hears this, she exclaims "Is that spelled with a "C" or with a "K"? Oh my god, it doesn't matter! They're both great!"
