Chronological error: Arletta McGreevy compares Fred to Superman even though this episode takes place around 1914 and Superman was not invented until 1933.
Arletta McGreevy refers to Fred trying to be a superman. This could be a reference to the play "Man or Superman" by George Bernard Shaw first performed in 1905. An experienced actress such as Arletta would have known about the play. and possibly played the female lead by 1914.
