Since its release at the end of last year, Pharrell Williams's Happy has been parodied, lip-synced and covered enough times to make the ex-NERD frontman break down in tears at the whirlwind success of the song in an interview with Oprah Winfrey.
The US embassy in Armenia had a go at lip-syncing the song, as did late-night talk-show host Jimmy Fallon while impersonating Vladimir Putin and Sarah Palin.
The latest endearing interpretation of the track comes courtesy of deaf campers and staff at the Deaf Film Camp at Camp Mark Seven in New York.
The camp, offering film-making education for deaf and hard-of-hearing youths, have recreated the lyrics of the entire song in American Sign Language.
Happy features on Williams's second solo album, Girl, as well as in last year's Despicable Me 2. With worldwide sales of over 10 million copies, the song has become one of the best-selling singles of all time,
However it missed out on the Academy Award for best original song.
That accolade went to Let It Go from Disney's Frozen.
