Here you will find the Poem The Sloth of poet Theodore Roethke
In moving-slow he has no Peer. You ask him something in his Ear, He thinks about it for a Year; And, then, before he says a Word There, upside down (unlike a Bird), He will assume that you have Heard- A most Ex-as-per-at-ing Lug. But should you call his manner Smug, He'll sigh and give his Branch a Hug; Then off again to Sleep he goes, Still swaying gently by his Toes, And you just know he knows he knows.
