Well I just had to find out about it, and got this:
Other than the obvious: a woman that seems of hindu (or Indian) descent singing a nursery rhyme about "niggers" and the obvious humorous remark Deon Cole makes "wasn't it ten little indians?"
, there is something else to it.
There
was a variation on the original nursery rhyme called "Ten Little Niggers" which was adapted in 1869 from the original and made popular in Europe in the 19th century by
Christy's Minstrels who performed as a
BlackFace Group.
And there is an Agatha Christie Novel that is now known as
And Then There Were None, it was originally called "Ten Little Niggers" in reference to the above.
I must say that if Cole wrote the material for the skit he sure dived into the stuff
