Weird Cousin is an episode in the Hey Arnold! TV Series.
The episode opens with Arnold and Lila at the movie theatre, where they check out several of the latest releases. Despite his excitement to see a movie with her, Lila tells Arnold that she only likes him as a friend and not in a romantic sense. Arnold is shocked and can't believe the news, thinking it makes no sense. Later that day, Arnold finds out that his (presumably maternal) cousin, Arnie, is going to be staying with him for the next four weeks, to which he runs home.
Arnie's revealed to be an odd and seemingly idiotic individual, who doesn't get along with anybody in the boarding house during a dinner. During his tenure, Arnie takes up his days attending P.S. 118, to which he is immediately disliked by all for his odd mannerisms, save for Lila, who starts to develop a crush on him. Despite attempting to be friendly to him, Arnold is upset that Lila likes such a disgusting individual such as Arnie more than the likeable and friendly person he is.
Helga notices this and tells Arnold not to be upfront about his crush and to play "hard to get". Arnold attempts this by showing affection to Helga instead, but Lila continues to fall for the misguided Arnie, causing Arnold to be greatly frustrated. Near the end of the episode, Arnold confronts Lila about her crush on the oddball and in response, Arnie breaks up with Lila. Arnold tries to comfort the sobbing Lila by putting his hand on her arm, but she tells him to stop and reminds him that she only likes him as a friend.
Upset once again, Arnold sits discouraged. Arnie then strikes up a conversation with Helga and reveals that the reason he broke up with Lila was because he is actually in love with Helga instead, who sits in stunned, horrified silence as he begins to ramble about his weird hobbies.
