Ernie has appeared in both of the "Sesame Street" movies. In "Follow That Bird", he and Bert searched for Big Bird by plane. Ernie piloted the plane, and eventually, after they found Big Bird, he flew the plane upside-down, singing "Upside Down World". However, after they lost Big Bird, Ernie blamed Bert. Ernie and Bert also appeared in Out to Lunch we're the host of this crossover special. In "The Adventures of Elmo in Grouchland", Ernie and Bert served as hosts, interrupting the movie whenever it looks like something bad is about to happen. Bert was worried about the bad bits, but Ernie reassured him by saying "Bert, nothing bad is going to happen!". Ernie reveals in "Sesame Street" Episode 257 that his favourite activities include watching parades, circuses and going to birthday parties. A typical Bert and Ernie skit has Ernie coming up with a harebrained idea, and Bert trying to talk him out of it ending with Bert losing his temper, while Ernie becomes oblivious to his own bad idea. Other sketches have involved Bert and Ernie sharing a snack by division, but finding that one of them has a bit more; Ernie humorously decides to try to make it even by eating the extra piece, which goes forth until the entire snack is all eaten up. Others have also involved Ernie eating part of Bert's snack he prepares for himself, and when Bert comes back from somewhere, Ernie tries to make several attempts to cover up the crime in front of Bert, which is not successful mostly. Some other plotlines involved Ernie wanting to play a game with Bert who wants to do something else; he continues playing until he gets Bert in, but when Bert finally wants to continue playing the game, Ernie is tired of playing, and wants to do something else. The age of Bert and Ernie is regularly discussed on forums. Nothing official has ever been said, but most consider the duo adults, as they do not appear to be highly dependent on others. One "Sesame Street Live" performer has commented that "I just kind of try to think like a six year old or a seven year old, because that's how old Bert is." However, Bert's twin brother Bart is depicted as a traveling salesman, which would mean Bert (and probably Ernie) are both adults. Ernie also appeared in the finales of "The Muppet Movie" and "The Muppets Take Manhattan", in the last of which he got a line.
