Observe, Record, Annoy

S42, E4: Oscar makes a mess in Grouchology class. His professor (Jason Jones) gives an assignment that includes three important objectives: observing, recording, and annoying. This will be the easiest A ever! Special guest Jerry O'Connell explains the word “observe.” Smile and say “cheese” for picture day at Abby's Flying Fairy School, and watch as Bert and Ernie become dog-walkers in Bert and Ernie's Great Adventures. Finally, Murray experiments with umbrellas, and pets are popular in Elmo's World.
