A horse is a horse of course of courseAnd no one can talk to a horse of course.That is of course unless the horseIs the famous Mister Ed!
Go right to the source and ask the horse.He'll give you the answer that you'll endorseHe's always on a steady course.Talk to Mister Ed!
People yakkity-yak a streakAnd waste your time of day,but Mister Ed will never speakUnless he has something to say!
A horse is a horse of course of courseAnd this one'll talk 'til his voice is hoarse.You've never heard of a talking horse?Well, listen to this...
"I am Mister Ed!"
