S1·E58 On a Roll

The Mad Hatter’s cousin Hedda Hatter is coming for a visit. Hedda is differently abled (she gets around in a wheelchair), and, when she writes that the only drawback is "stairs", the Wonderland gang thinks she means "stares", so no one will look at poor Hedda. Once the confusion is cleared up, Hedda teaches everyone that people in wheelchairs can do anything an able person can.
