Write really overly-funny super hilarious comedy 17+ short Scooby-Doo cartoon parody transcript that always starts with the villain moment first, then the gang hearing about it once they reach the area, and then the rest based on my prompt: (but make it more funnier adult comedy where the gang constantly make fun of and question physics that ain’t possible or don’t make any sense and why, they always mistake some character for a famous person because of their surname being literally the same as a real life celebrity, forcing the character to correct them angrily, Shaggy is often the one who would mishear a location name, leading to someone correcting him angrily and why, Velma is often rudely interrupted by the gang insulting her when she says something too scientifically smart,  they always know that a place they are going to doesn't sound like it exists, they also know something in a place they go to shouldn't even be there as it makes no sense, they question names of things or people and why, and even question the motives and why (Plus they constantly do  pop culture references and jokes, and mentions of famous people, games, songs, and shows occasionally in the prompt: Also, Velma is too smart, Shaggy is the dumbest and hungriest, Fred is always the one thinking a guy they encounter is a celebrity due to the surname being the same, Daphne is a sarcastic one, Scrappy is overly-heroic and thinks he's a superhero, and Scooby (Self-proclaimed himself as Shaggy's personal superhero), being Shaggy's best pal, always sticks up for Shaggy when he's insulted by Fred with verbal abuse and protects him from any villain that questions his dumbness (which always happens whenever Shaggy's dumbness comes out of his mouth, from start, middle and end of script). Scooby also hates when people correct Shaggy. 

During dinner at the White House, Velma is interviewed about NASA by a news reporter Jessica Byline. Shaggy and Scooby make faces at the camera til an annoyed Daphne pulls them back. Then, Jessica interviews the Ambassador of Klopstokia, who is interested in the new space program, but his wife is more interested in tea. Then, Jessica interviews Senator Bullhorn, who along with his wife, is rather against the space program. However, just as the President is about to make an announcement to the people about the space program, the Ghost of George Washington appears. The crowd runs away in a panic, but Shaggy and Scooby give him the slip in a room of statues. Meanwhile, Scrappy, Daphne and Velma find a small, brass eagle, their first clue. But when the people try to catch the ghost, they get Scooby by mistake and accuse him.

Meanwhile, Scooby's parents, Mumsy-Doo and Dada-Doo, hear about this on the news. So they pack up to go to Washington D.C. and help him. Mumsy-Doo makes sure to bring Scooby's galoshes.

Back at the White House, the President explains that he knows they weren't responsible for what happened and agreed to let them go if they help catch the real culprit. The gang follows Marilyn Maxie for their investigation. During this, she explains that the brass eagle is a bedknob to one of the beds in the guest room. So the gang decide to search the rooms to see which one is missing a knob. Shaggy, Scooby and Daphne, disguised as room maids, search the knobs in the Ambassador and his wife's room, but find nothing. Scrappy and Velma, disguised as pest control people, search the bed in Senator Bullhorn's room, but still nothing. Then, Shaggy and Scooby encounter an arm coming from a painting on the way to check out Marilyn Maxie's room, which used to belong to President Ulysses S. Grant. Grant's ghost appears in the door. The gang run in the other direction, but run into the Ghost of Theodore Roosevelt. After escaping into the room and barricading the door, Daphne finds a brass eagle that fits on the bed, but when they put it on, a trap door leads them into a secret passage.
