Denver Nuggets big man Nikola Jokic is a gift that just keeps on giving. Recently, his infamous old passport — which contains a photo of a young and healthy Jokic — was the center of attention in a new Serbian add.

This brief clip should serve as a bit of a mood-booster to anyone who may have been having an off day.

Jokic is one of the funniest players in the league we have right now — hence his moniker, The Joker — and this recent advert is yet another testament to his hilarious sense of humor. It's great how the 7-foot big man is able to freely poke fun at himself and his past (and present?) issues with his weight.

One thing we are sure of, however, is that when he's on the basketball court, it's all business for the 24-year-old Serbian international. Last season, Jokic led the Nuggets to the second seed in a ruthless Western Conference, en route to his first-ever All-Star nod.

More of the same is expected from Jokic this coming campaign, and while Denver did not exactly engage in what was a crazy offseason, they are still widely regarded as one of the serious contenders in the West. Jokic, entering only his fifth season in the NBA, will have a huge part to play in how his team fares in the new season, but if his development over the past few years have been any indication, then surely, the former 41st overall pick is in store for another big year.
