Riley is always singing her own songs. Songs where she makes up the tune and the words. Sometimes it's two or three songs mashed together and sometimes we just have no idea. In this episode, she is playing the mandolin and singing. The first song is "Jesus was a Weather Man" to the tune of "Mary Had a Little Lamb".
The words are hard to hear but it is something like:
"Jesus was a weather man, weather man, weather man,
Jesus was a weather man...today."
And her second song she calls the "Number Song". It goes:
"1, 2, 3, 4, 5, 6, 7, 8, 9, 10...It will never end, it will never end, it will never end
You keep on doing your numbers, it will help you do it today."
Guess "today" rhymes with a lot of things. Or not in this case.
