Being Married to Poison Ivy

I married a woman named Poison Ivy.
My decision was rather rash.
For she only married me for my money,
And she took all of my cash.

I was mesmerized by her beauty.
She had a fatal charm.
I proposed to her immediately.
I didn't see the harm.

Now Poison Ivy is fooling around.
She's with another guy.
Meanwhile, I'm laying in bed itching
Because of her countless lies.

I plan to divorce Poison Ivy.
I'll be doing it very soon.
I'm tired of looking like a worn out pup
From an early morning cartoon.
