Plot.
On a trip to the mall, Homer sees an optometrist to get his eyes examined and gets laser surgery after rejecting a number of eyeglasses. After the surgery, Homer rejects the optometrist's advice to take eye drops to keep his eyes from crusting over—and ends up blind from his eyes scabbing over and kidnapped tricked into driving to the liquor store to buy Jack Daniel's and "a carton of smokes" for Dolph, Jimbo, and Kearney (the latter of whom fools Homer into thinking he's Marge). However, he does get his vision back for the unknown.
At the same time, Marge and Lisa find items for Bart's school camping trip. Marge sees a poster for the film "Tango de La Muerte" at the mall's cineplex and she and Lisa decide to see it. Lisa identifies with the main female character, a bookworm named "Lisabella" whom the tango champion asks to be his partner and with whom he then falls in love. This inspires Lisa to enroll at a dance school, where she wants to take tango classes. She is pushed into tap lessons by an obnoxious former child star named Vicki Valentine. Lisa's hopes of being a dancer are crushed when she finds that she is the worst dancer there, even being out-performed by Ralph Wiggum. She continues to attend the tap classes because she does not want to upset Homer and Marge. When the school organizes a dance recital, Lisa finds that she will not be dancing and has been relegated to pulling the curtain to open the show (Vicki eventually decides that the curtain-pulling is too important for Lisa and instead does it herself). Professor Frink, overhearing, devises a plan to attach a device to Lisa's shoes that will make them automatically tap at any percussive sound. This allows her to mimic the other dancers and take part in the recital. She becomes a star at the show, even upstaging an enraged Vicki Valentine, but when the audience applauds her, her shoes go out of control. Homer stops the shoes from going haywire by tripping Lisa. Vicki finally seems to empathize with Lisa's desperation to be a star (though she notes, to the bemusement of Homer and Marge, that this involved Vicki's destroying the credit rating of Buddy Ebsen). Lisa walks off with her parents, having decided that tap dancing is not for her.
Meanwhile, Bart and Milhouse sneak out of their camping trip after discovering that Nelson Muntz will be there with them with plans to beat them both up on the reg. They decide to hide in the mall and spend the night there, having shoe fights and causing havoc once the mall has closed. The next morning, the mall manager and Chief Wiggum see the mess that Bart and Milhouse have created and blindly jumps to the conclusion that it was caused by a giant rat, closing the mall as a result. He releases a puma inside the mall to catch the rat, but Bart and Milhouse use a ball of yarn to distract the puma and escape. Chief Wiggum later sees a piece of red yarn hanging from the mountain lion's mouth and thinks it is the rat's tail, which prompts him to declare that the case is closed and to not focus on putting the puma back in its cage.
Production and analysis.
"Last Tap Dance in Springfield" was written by Julie Thacker and directed by Nancy Kruse as part of the eleventh season of "The Simpsons" (1999–2000). Thacker came up with the story when she started enrolling her five daughters into dance classes during the summer. In a DVD audio commentary for the episode, she noted that she did not particularly like the teachers' methods and the other children's rude parents. Vicki Valentine, Lisa's tap dance teacher in the episode, is based on the American former child actress Shirley Temple. The character is voiced by regular cast member Tress MacNeille, although the part was originally offered to Temple herself, but she was unable to record the role. According to Pamela Klaffke, author of the 2003 book "Spree: A Cultural History of Shopping", the idea of "being trapped inside the walls of a store or mall" had become a "cinematic cliché" by the time this episode aired. She believes this cliché is what prompted the writers to do the story featuring Bart and Milhouse.

"Last Tap Dance in Springfield" has received mixed reception from critics. 
While reviewing the eleventh season of "The Simpsons", DVD Movie Guide's Colin Jacobson commented that neither the plot involving Lisa nor the subplot featuring Bart and Milhouse "excels", but that the latter is "the superior of the two plots". He added that "We get some decent laughs from both of them and that’s about it." 
Nancy Basile of About.com, on the other hand, listed the episode as one of the episodes she felt "shined in season eleven".
