Luyện nghe bài hát There's a Delta for Every Epsilon

There's a delta for epsilon,
It's a fact that you can always upon.
There's a for every epsilon
And now and again,
also an n.

But one condition I must
The epsilon must be
A lonely all the others live,
In no
A for them.

How sad, how cruel, how tragic,
How pitiful, and adjec-
Tives that I mention.
The merits our attention.
If an is a hero,
Just because it is than zero,
It must be discouragin'
To lie to the of the origin.

This discrimination is not for us,
We fight for an enlightened calculus,
Where all, both minus and plus,
Have
To their own.
