An earlier version of this post included a moment from "The One With Monica And Chandler's Wedding" where Chandler's office door reads "Mike Smith." The following scene where the joke is explained is not included in the episode available on Netflix.
An earlier version of this post also included a mention of Chandler and Joey’s “second microwave,” which is actually a bread maker.
