Tunak Tunak Tun is a pop love song that is created by Punjabi artist Daler Mehndi . The song was released in 1998. It has become an internet meme because the tune is catchy and the dancing was hilariously entertaining. The music video came out in 2001. The music video took place in computer-generated backgrounds such as one feature in St. Basil’s Cathedral in Moscow. He wanted to create a video using him instead of beautiful women dancing. The song was still a successful hit due to its foreign language and unusual dancing. 
Rick Roll’d is an internet prank or joke. Rick Roll, Rick Roll'd or Rick Rolling is an internet spam trick in which people post a link to a Rick Astley video on Youtube, but say the viewers of the video are being led to another video, usually proof of unconfirmed gaming news or trailers.
Joe Jonas made a music video of single ladies. In which everyone was considering the face he is gay. In which he only made the video because he was doing it for the fans because they asked for it. But, the fans are gay guys. It makes sense right? This single ladies video is posted on youtube.
Numa numa

Was first popularized by Gary Brolsma's release of Numa Numa Dance onto Newgrounds.com on December 6, 2004.

The video shows Gary Brolsma wearing headphones and lipsyncing to the audio of the original O-zone track whilst moving his head, shoulders and arms gesticulating to the music in an animated and earnest manner.

Brolsma was sitting at his computer filming himself with a webcam, which thus provides a tightly restricted frame of action giving the video and its genre a visually distinct character.

This video has been viewed over 34 million times on YouTube.

His original video was named 41st in the 2006 broadcast of 100 Greatest Funny Moments by Channel 4 in the UK
On April 27, 1997 the entire N64 world did a collective barrel roll with the release of Star Fox 64. Whether it was the inane manner in which Peppy repeated the exact same sound byte throughout the game or the exhilaration of completing a 360 degree longitudinal rotation along a helical path
“So I herd you liek mudkips” was one of many memes swept up in the popularity peak of April 1st, 2008.  YouTube was suddenly flooded with Mudkip videos, all with their own humorous twist at an attempt of originality

Awesome Smilies are popular on 4chan, Something Awful, and more.  The emoticon was first designed my an anonymous female artist on the forums and Pokemopols and soon spread quickly over the internet.
The debate over whether pirates or ninjas are better and who would win in a fight.  Statistics and common sense show that ninjas are the superior warrior and do in fact pwn pirates.
