Not recommended to listen to this song while operating heavy machinery.
As with the rest of the abecedary, the goal is to teach the word by means of song.... and nothing says lethargic like a slow 3-chord song where the singer falls asleep during the song, am I right?
Boy, am I sleepy.
I have no energy today.
I'm so lethargic.
So very, very sleepy.
I can't remember what I wanted to sing about.
