One Word Means Nothing; Two Words are a Work-Out

I used to be afraid to exercise
Because the floor-length mirrors
And the women in purple sweats
And the radio playing Koo-bee-La-la
Made me feel like scissors on the radiator

You probably want to know why scissors
Could be a point of self-reference for me
I can say that my mother used them to clip
My dresses because she wanted me to have
Better legs, but that would be a lie.

I only wanted to say scissors; now I’ve said it:
Scissors. In conclusion, I am still afraid to exercise.
