(I give the title exactly as they give it.)

TRISCADECAPHOBIA

Triskaidekaphobia,
I got triskaidekaphobia,
And triskaidekaphobia
Has got me.

I open doors for claustrophobia,
And I wear glasses for myopia,
But that triskaidekaphobia
Won't let me be.

Now one, two, and three, they don't bother me,
And neither does four, five, six, and seven.
But I can't conceal the fear that I feel
When I hear the number that's two plus eleven.

I'll be living in utopia*
In a glorious utopia*
If triskaidekaphobia
Sets me free.

[*I think one of these words should have been "euphoria."]
