The Shower Principle

In the episode, Liz (Tina Fey) realizes that every year in her life is exactly like the last and uses this knowledge to her advantage; Jack (Alec Baldwin) searches for a business pitch that will transform Kabletown; Jenna (Jane Krakowski) deals with a theatrical curse; and Tracy (Tracy Morgan) has trouble with the IRS.

He tries to distract himself with showers and golf, operating under the theory that putting his mind elsewhere will bring inspiration.

Jenna refuses to perform in a sketch based on Macbeth due to her belief in The Scottish Play curse.

Liz casts Cerie to make Jenna jealous, which is met with immediate success.

Tracy, realizing that it is almost tax day, starts to remember multiple income sources and needs to generate some cash by starring in a movie.
