Add The Avengers to the list of movies and shows Sesame Street has flawlessly spoofed. In its latest parody, Ultron is Bon Bon, a vegetable hater hell-bent on “desserting” all of Earth’s veggies. Luckily, Dr. Brownie, Onion Man, Captain Americauliflower, Black Bean Widow, Mighty Corn, and Zuchin-eye come to the rescue. Except when Dr. Brownie (a.k.a. the Cookie Monster) devours most of their costumes, it becomes pretty clear that crime-fighting isn’t really their forte. (“My shield! That’s what makes me special!”) So it’s pretty much spot-on the actual Avengers — especially Hawkeye. Poor, useless Hawkeye.
