Blergh. I just found out that the routine everybody is talking about is mostly a rip-off. There was a competitive dance group that did a routine to Single Ladies (Dance 7 Years Old Original if you want to "search" for it) and Abby stole their costumes. The ones on this show are identical except she changed the original red to blue.
What a loser, I hate people who are unoriginal. I hate ones who steal the work of others even more.
