Funny keyboards have been floating around since the invention of the keyboard. Through Photoshop and other edits, regular keys on a keyboard are edited to say stupid yet funny things, such as the edit shown below:

in which keys are replaced to say humerous things, such as "Exploding Mudkips" or "Leave Britney Alone", commonly other memes are used on the keys.

Several websites themselves feature Funny Key Creators, where people can make their own keys. Funny keyboards are used as hoaxes and in some cases, copied in real life, in which the keys are actually edited with funn inscriptions.

No matter what the idea or creator, funny keyboards all serve the same purpose: to gain laughs from others. People often believe they are real.
