Sakka Cooper!!!

So I was sitting with the boys in the rocking chair singing songs before they went to bed (something we do almost every night). As usual, I asked them what songs they wanted to sing and at first they ask me to sing the "regulars". Then Cooper asked me to sing the Cooper Song.... wasn't sure what that was, but we made up one. Of course, Carson requested the same. Then Cooper asked me to sing Sakka Cooper.....again, no clue. Carson jumped in and wanted the Sakka Carson and Cooper song. I asked them what "sakka" means. They both answered "it's time for bed Carson and Cooper". Then they commenced to laughing hillariously at themselves for the next several minutes. They were quite impressed with themselves for coming up with that..... Of course, I had to make up a Sakka Carson and Cooper song.
