13 Mistakes In 'Friends' You May Not Have Noticed

List Rules
Vote up the 'Friends' mistakes you missed.

Friends is one of the most enduringly popular sitcoms, alongside the likes of Seinfeld and The Golden Girls, in spite of the countless Friends continuity errors and poorly aged jokes. The show offers audiences relatable story lines, unrealistic expectations of life in New York City, and most importantly, a model for the value of lasting friendships - which is likely why so many fans are willing to look past certain conspicuous Friends mistakes, like the fact that Rachel's birthday is inconsistent, or that Joey and Chandler's Magna Doodle drawings often change mid-scene. 

Friends errors are more fun to acknowledge after your seventh viewing of the series; even the Friends stand-in mistakes alone are almost like little Easter eggs hidden throughout.
