Samantha on Thin Ice

Bewitched

Tabitha wants to learn how to skate, and Samantha agrees to take lessons with her in the mortal way. When Tabitha falls down constantly, Endora cannot take much more and decides to bewitch Tabitha's skates so that Tabitha becomes a terrific skater. Tabitha is bound to be the next Tara Lipinksi if Endora doesn't take that spell off of her. So Endora does and Tabitha is back to being a poor skater again.
