Friends: 16 Easter Eggs You Totally Missed
10. Magna Doodle
Along with Pat the Dog, another great background element of J-Man and Channie's apartment was the Magna Doodle, which sat on the back of the door.
The very first doodle to appear on the door said 'Joey call your dad', and the final one was an image of a volcano. It factored into the plot in TOW Mac and CHEESE, with Chandler ineligibly scrawling the note for Joey on it, and referenced the episodes themselves - champagne appeared on it when Mike and Phoebe were getting married, and there was an astronaut for The One Where Ross Got High.
All of the doodles were drawn by crew electrician Paul Swain, who sadly never received the due credit he received for this sterling work. Paul Swain, I salute you.
