Rebecca Black - Friday
This was a pop song released in an entirely serious manner, but because of it being so aggressively awful the internet picked up on it as a joke and have shared it around. Despite the comments of how shallow the lyrics are, and how bad the quality of the video and singing are it has received over 146million views! That's crazy. No doubt it is awful, but it is awful to a degree that it's funny and makes people want to show other people how awful it is.
Annoying Orange
Annoying Orange consists of a man's face edited on to an orange, being annoying, talking to different fruit. Despite being annoying the interactions are funny, and this is a video series that regularly gets over 20million views per video. The quality of the effect is passable, but the idea is absurd enough to get recognised.
Gingers
This started off as a video blog from an annnoyed ginger kid who got angry on camera about people saying ginger people don't have souls. The person's appearance and disposition as well as his 'performance' have made it a comedy hit throughout the internet. and have spawned several parodies (even from famous TV shows like South Park:
Down On Me(With Me And 50 Cent)
Hide Your Kids, Hide Your Wife
This viral spawned from a funny interview segment on TV that has been remixed countless times.
Old Spice
This is one of my favourites and one of the most successful viral series for a product. It is funny, entertaining, well produced and sells the product very well. It features a lot of effects that I would not be able to produce but the idea is lavish, outlandish and funny.
