THE LUCY SHOW EPISODE GUIDE

Lucy and Viv decide to update their education, so they enroll in an adult education course in chemistry. Viv soon regrets letting Lucy talk her into joining her for a night-school chemistry class.
Lucy gets carried away with herself, trying to invent a youth serum and develops a huge ego between explosions. Viv and the professor decide to teach her a lesson. They make her drink her own concoction, which acts as a sedative. When she awakens, she's horrified by the results of her youth formula. Vivian has made Lucy up with horrifying make-up.
Bloopers: When Lucy is about to do her experiment she asks Vivian to give her some glass tubing. Vivian partially flubs her line by saying there is no "gas" tubing.
