Shirley's Operation - S3.E10

The gang is rehearsing the play ""Alice In Wonderland"" so they're all in costume: Shirley is Alice, Laverne is the Mad Hatter, Lenny and Squiggy are Tweedle-dum and Tweedle-dee. Shirley faints on the couch and is taken to hospital where it is discovered that her appendix is about to burst. Fearful that she is going to lose her hair for the operation, Shirley hides while everyone else tries to find her before her appendix bursts.
