ABO's

Elsie is in love with the Alphabet Song. Sometimes she will sing it 10+ times in a row, varying her voice and doing all sorts of silly things. Then the other night she sang it to me a new way:

"A-B-C-D-E-F-O, H-I-J-K-L-M-N-O-O, Q-R-O, T-U-O, W-X-Y and O. Now I know my ABO's, next time won't you sing those. With me."

She has sung the last line a few different ways ("Next time won't you sing the O's song with me"), just out of the blue. We have never tried to get her to sing it differently or anything, she just came up with it herself, and she figured out all the right places to put the O's.
