She is not a blonde!

"She's not a blonde." Bill said.
She flung her blonde hair
in a seductive manner.

"How can you tell?"
I had to ask.

"She is too smart.
I bet you a bill,
she is a brunette."

I took the bet.

For she was as dingy
as a tossed about bouy.
She came and stood next to me.
Her blonde hair, I could clearly see.

We chatted about chit
and I bought her a drink.
I think.

I finally got the nerve,
"Can I see your roots?
So I can tell rather your a blonde
or a brunette."

Shyly she replied, "Okay!"

She was a little surprised
but didn't stop me
when I pulled her pants down
and saw that...
she was a Red Head.
