There's this character in a show named Bob who is a little different from everyone else. Maybe his personality is a bit quirky, or perhaps he's abnormally short compared to everyone else, or maybe he has a third arm. The other characters wouldn't mention it (or maybe they will), but one episode there comes a time where Bob gets annoyed or embarrassed at his differences. Luckily though, 10 episode minutes later it just so happens that the cast gets themselves stuck in a situation where said difference comes in useful and only someone with said difference actually is able to solve their predicament. Ooh, how convenient.
This trope comes up either for a bit of character development for Bob, or as an Aesop of sorts towards the audience where the lesson is "Be Yourself" or "Don't be ashamed if you're not like everyone else".
