Your Stretchy Pants

You might wonder
What is wrong with me
I can tell you after a glance
I can't take my eyes off of you
When you wear your stretchy pants
They hug you close just like skin
Looking away when you wear them
Should most certainly be a sin
So don't look at me so dim
I just can't help myself
I am a naughty elf
With carnal thoughts
When you wear your stretchy pants . . .
