The Singing Shark is a 4-pane comic featuring an illustrated shark singing the phrases "I'm a shark! Suck my diiiiick!" The comic inspired an exploitable series, including various animals, people and objects with speech bubbles containing the snowclone "I'm a X" and the phrase "Suck my dick!"
The earliest known instance of the original comic strip was uploaded to YouTube on December 23rd, 2006 with no mention of its creator. The art is commonly attributed to Chris VanGompel's now-defunct webcomic Hockey Zombie, which featured a comic titled "The Singing Shark" on February 20th, 2007, in celebration of Discovery Channel's Shark Week, an annual programming event celebrating various species of sharks.
On February 15th, 2007, five days before "The Singing Shark" was featured on Hockey Zombie, a thread was posted to the eBaum's World forum requesting the comic. On February 23rd, user zlopez replied to the thread with a link to the comic hosted on the image sharing website ImageShack. On March 17th, a flash animation based on the comic was shared on deviantArt. Ten days later, a definition for the phrase "I'm a Shark!" was submitted to Urban Dictionary, citing Hockey Zombie as its origin.
The earliest archived appearance of the phrase on 4chan was posted in a pick-up line thread to the /b/ (random) board on May 7th. On July 14th, the comic managed to earn a "GET" by being the 3,300,000th post submitted to 4chan's /b/ board. Throughout 2008 and 2009, parodies of the comic and accompanying catchphrase appeared on FARK, the off-topic forum WTF.com, gaming forum Explosm.net, the IGN forums and Destructoid. In 2010, a Facebook fan page was created for the phrase "Suck my sick, I'm a shark", which received 1781 likes as of August 22nd, 2011. The phrase is sometimes used as a tag on Tumblr as an insulting retort.
