Kelley was a very famous Zimmer Twins account shared by three sisters from Pennsylvania.
After quitting in 2011, they came back for a short period of time in 2012. They renewed for Christmas 2012 and Christmas 2013, but not since then.
Ever since they joined in 2010, they have been well-known for the humour. They have a lot of Crowd Pleasers, which TinyRobot pointed out when putting them on the spotlight in May 2011.
Some of their movie titles featured alliterations, e.g. Class Craziness (a famous Crowd Pleaser of theirs from May 2011) and rhymes, e.g. Rude Food Mood (a famous Must-See of theirs from March 2011).
