Maria's blind friend, Sue, pays another visit Sesame Street : Season 13 Episode 116

Maria reluctantly allows Forgetful Jones to help her out in a situation - her friend is arriving any minute and needs Forgetful to keep watch. She gives him the important information he needs - her name is Sue, she'll have a guide dog with her (she's blind), wearing a harness and that she'll wait at the stoop for Maria's return. Forgetful forgets, as usual, what he was supposed to remember, when Sue (Sue Harden) arrives. He's able to piece together the clues.
