| Character Information
Jack LaLanne is an American motivational speaker and nutritional expert.
When the residents of the Springfield Retirement Castle were on a sinking boat, after Mr. Burns' yacht sailed through it, Jack LaLanne appeared from the crowd and decided to save everyone, the Jack LaLanne way. He then grabbed a rope, put it between his teeth, dived into the sea and started swimming back to shore. On the way back, the front of the boat broke off. LaLanne looked back at the rest of the boat before he carried on taking the front part of the boat with him back to shore.
