 A special rubber and foam turkey was created for Joey and Monica to place on their heads for sanitary and insurance reasons . A weaving , invisible to the audience , was placed in the middle of the turkey to allow the character to see . Chandler 's " flock of seagulls " hairstyle , mentioned in a previous episode , was based on the 1980s time period . For safety , the scene where Monica severed Chandler 's toe was pre @-@ shot . Originally the sound of a knife slashing through Chandler 's shoe was placed , but according to Crane it " got a little too graphic " . Dramatic music was dubbed over instead .
