I have a tough job sometimes, and when the orders come from above to sit there and troll YouTube looking for funnies, I am only too happy to oblige. I offer my services to you so that a days worth of searching can be condensed into 30 minutes of visual stomach-rumbling ecstasy. So without further ado, here are 10 funny YouTube mash-up and remix videos that are guarantee to give you hysterics.

Warning: Some of these are very much NSFW. Don't let your children see, and don't watch in the workplace - unless you work in one of those really cool places where everyone's really chilled and is likely to gather round and demand you play it again. Then the rest of the day is spent showing off everyone else's YouTube favourites - in which case it's probably okay. Also, we accept no responsibility for medical injuries arising from hot coffee being spilled, splat, or laughing so hard your rib cage bursts. You have been warned.

Harry Potter and The Homo-Erotic Subtext [NSFW]

As a true Harry Potter fan, I feel dirty just mentioning this. This is straight from the labs of CassetteBoy, one of the founders of mash-ups today whose namesake comes from cutting and splicing together tapes.

Dragon's Dirty Den [NSFW]

Here's another from CassetteBoy, this time pieced together from Dragon's Den, a UK TV series in which members of the public pitch their business ideas to a group of investors, hoping to get a cash investment. It's a quite a long one, but it's good!

Sesame Street - The Count Loves To £%$@ [Imaginary NSFW]

This video doesn't actually contain any bad language, so if you're hearing dirty things it's entirely in your mind! You should be ashamed of yourself!

Brian Cox - Wonders of the Stoner System

Brian is an amazing scientist and a passionate BBC presenter (and was also the keyboard player for 1990's one-hit wonder band D:Ream with their anthem "Things can only get better"). His programs just beg to be remixed, and this one had me in stitches. Sorry Brian - we love you!

French Jedi Farmers

What happens when French farmers blocks the road? Obviously, hilarity ensues. But just imagine if they had lightsabers too. Now that's just going to be 9,000 times better.

That Jean-Luc Picard

From the Jandrewedits team, this is just one in a long series of Star Trek: The Next Generation mash-ups, all of which can be viewed here. Be sure to check out the painstakingly made full series too, most of which are equally as hilarious.

Kill Mario

What happens when you add Super Mario sound effects to one of the best Kill Bill scenes? It's a bit slow to start, but that just makes it all the better.

Charlie Sheen: Winning

In which Charlie offers quick judgements on a variety of controversial topics (Tinky Winky's Purse? WINNING!)

Muslamic Ray Guns - The EDL Anthem

A tad topical perhaps, but this thoroughly British geyser echoes a sentiment and mentality rampant across Britain. Whatever your point of view, this Mashup/Remix is a classic.

He's actually saying "rape gangs", not ray guns - and the EDL refers to English Defense League, an extremist Christian right-wing group in the UK (yes, we have nutters too, America!)

The Presidents Speech

Originally from the Jimmy Kimmel Live show, whoever that is - it's a parody trailer of the mediocre movie, The King's Speech. Enjoy.

Well, I hope you enjoyed that, because I sure had fun finding them.
