Celebrity cameos have become a longstanding TV tradition. Not only do they help to provide levity, but they also allow us to see a side of our favorite celebs that might have otherwise gone unnoticed.

There are countless examples of celebrity cameos that have helped to prop up and even save a series from disaster, and then there are those that just feel out of place. Have a look below and check out these 15 weird celebrity cameos in TV shows I completely forgot about.

Joel McHale as Warren in 'Sons Of Anarchy'.

I'm a diehard fan of Community and a huge Joel McHale fan to boot. But it was clear to see that the comedic actor was completely out of his element during his admittedly short tenure on Sons of Anarchy.

Justin Bieber as Jason McCann in 'CSI: Crime Scene Investigation'.

Justin Bieber is an incredibly talented artist, the likes of which we may never see again. However, a dramatic actor he most assuredly is not and it showed painful clear.

In fairness, New Girl had already gone the way of the dodo by this point and Megan was only brought in to be a placeholder until Zoey Deschanel returned from mat leave. Despite her best efforts, Megan just didn't gel with the cast.

Snoop Dogg in 'The Trailer Park Boys'.

Don't get me wrong, Snoop Dogg's personality gelled perfectly well with Ricky and the Sunnyvale gang. It just was so odd to see one of the greatest rappers of all-time appearing on a low-budget Canadian-made mockumentary series.

Stephen Hawking as Himself in 'The Simpsons'.

Stephen Hawking was one of the most brilliant minds ever to walk the earth. At first thought, you might think that an appearance on The Simpsons would've been below him — but you'd be mistaken.

George Clooney as Sparky in 'South Park'.

It may surprise many to learn that George Clooney is a huge fan and supporter of South Park. What's even more shocking is that for George's first celebrity cameo, he played a homosexual dog that didn't actually speak.

Shawn Mendes as Macallan in 'The 100'.

Shawn Mendes is a huge nerd and lover of all things science-fiction. He became obsessed with The 100 and decided to tweet the showrunners asking for a cameo appearance in the series.

Ed Sheeran as a Lannister soldier in 'Game Of Thrones'.

Casting Ed Sheeran, arguably the biggest artist in the world at the time, as a singing soldier in the Lannister army was a mistake. It completely shattered the veil of illusion and brought nothing to the story, whatsoever.

Larry David as himself in 'Hannah Montana'.

Larry David is the furthest thing from the comfy cozy persona Disney has crafted over the past eight decades. The only reason why he appeared in Hannah Montana was that his two daughters were massive fans of the series.

Bruce Willis as Paul Stevens in 'Friends'.

Normally when we see Bruce Willis on screen, he's either kicking somebody's ass or blowing something up. It turns out that the only reason he agreed to cameo in Friends was due to the fact that he lost a bet with Matthew Perry.

Neil Gaiman as Himself in 'Arthur'.

I would expect to see Neil Gaiman pop up in Supernatural or perhaps some other type of Vampire CW series. But watching the creator of "The Sandman" and "Coraline" in a kids' show about a talking ant-eater just seems out of place.

Britney Spears as Abby in 'How I Met Your Mother'.

I'm a true '90s kid, so you know I have undying love and appreciation for Britney Spears. I just could never wrap my head around her agreeing to portray a conquest of Barney Stinson.

Paris Hilton as a Leshy in 'Supernatural'.

Fans of Supernatural know that the show has a penchant for being meta. Casting Paris Hilton to play herself, then making reference to a horror movie she starred in alongside Jared Padelecki may just be the most meta thing the series ever got away with.

Former Senator John McCain as Himself in 'Parks And Recreation'.

One of the most underappreciated aspects of Parks and Recreation was the series' ability to secure real-life politicians as guest stars. What I wouldn't have given for Leslie to have turned around right at this exact moment.

Bob Dylan as himself in 'Dharma And Greg'.

Bob Dylan is arguably the most famous musical recluse currently alive today. The legendary folk singer doesn't make a habit of giving interviews or making public appearances, so how or why he agreed to cameo in Dharma and Greg is beyond me.
