If I haaaaave to...

For the last six days I have had a song stuck in my head. And if I haaaaave to have a song stuck there, at least this is a good amusing one. Now, let's see if it is contagious:
Do your ears hang low
do they dangle to and fro'
can you tie them in a knot
can you tie them in a bow
can you throw them over your shoulder
like a continental soldier
do your
ears
hang
low!
