Sesame Street's iconic duo Bert and Ernie are brought to life with an impressive amount of dedication by cosplayers. Created by Jim Henson and Don Sahlin, the duo made their debut in 1969, when they were puppeteered by Henson and Frank Oz. An odd-couple duo who live together and often find themselves disagreeing, Bert and Ernie have been mainstays of Sesame Street since their debut and are two of the series' most recognizable characters.
