S4·E35 To Beetle Or Not Beetle

Lydia has to write a paper on Shakespeare for her English class, but can't understand his plays. So BJ takes her to the Neitherworld to meet Shakey's characters, who turn out to be rather disgruntled with their roles. When they kidnap Lydia and try to force her to rewrite their plays, BJ must rescue her; then it's up to the both of them to cure Shakespeare of his monumental writer's block.
