Cool Uncle

""Hey kids! Uncle Bob's here!"

"Yay! Uncle Bob!""

Lots of fictional families seem to have that one uncle that all the kids just love. Most often, he's a young bachelor who has no intention of settling down any time soon, though he may have a girlfriend. He may travel a lot and wow the kids with stories of meeting celebrities and traveling the world (and if so, he always brings back the coolest souvenirs, which he naturally gives away as presents). Or he may be well-off and spoils his sibling's kids whenever they're together.

Regardless, he will often be secretly be envious of the stability and loving home life that his brother or sister enjoys, even as he boasts of his own independence. The uncle may be the Black Sheep of the family.

This trope is usually male, but the role will occasionally be taken on by an aunt.

Animation

 * Uncle Iroh was this to Zuko during his childhood in Avatar: The Last Airbender. As he aged, Zuko treated his uncle as more of a buffoon as he (Zuko) came more and more to resist Iroh's guidance -- which encouraged Zuko to reject his father's philosophies about honor (along with Iroh's tendency to distract Zuko from Wangst via Obfuscating Stupidity). Toward the end of the series, Iroh again becomes Zuko's Cool Uncle.

 * Nancy and Peggy's Uncle Jim, also known as "Captain Flint", in the Swallows and Amazons series. He lives on a houseboat, owns a Pirate Parrot, and has travelled all over. A great part of the first book revolves around his nieces starting a private war with him, since he's taken up writing and become distant, therefore, in their minds, ceasing to be cool.
 * Discworld: City ruler Lord Havelock Vetinari is the epitome of cool and cunning. But from the novel Night Watch onwards, the character of his only living relative, the aunt alluded to in Guards Guards, is opened up a little: it is hinted that Vetinari learnt a lot of his skills from Auntie Bobbie (Lady Roberta de Meserole), who is a political manipulator, a Seamstress where she needs to be, possibly one of only a handful of female Assassins, and a lady of guile, insight, cunning and wisdom. She has certainly raised Havelock in loco parentis after the undetailed death of his parents. A second wise woman in Havelock Venturi's life, an aunt-like character, has been the vampire Lady Margollota (although some interpretations hint at a sexual relationship.)

Live Action TV

 * Everybody Loves Raymond: In one episode, Raymond laments the fact that Robert is always willing and able to play with Raymond's kids when he comes over, never seeming to be too busy or too tired to do so. When Robert discovers this, he explains that he's only able to do it because he only ever sees the kids for an hour or so at most. Raymond, meanwhile, cares for his children effectively all the time, and shouldn't be ashamed that he lacks the energy to "Play Monster" with them all day.

According to Buffett, this all actually happened back when he was 17.

Red convertible '65

Headed home to Mississippi, he'd been around the world

That black sheep uncle of mine

His ship had come in, he was looking to sin

Singing his own song

When he yelled from the drive, my heart came alive

"Jimmy boy come along""
