Pack it up, pack it in, let me begin
I came to win, battle me that's a sin

$$ \lim\limits_{x \to \infty} \exp(-x) = 0 $$

Get up, stand up (c'mon!) see'mon throw your hands up
If you've got the feeling, jump across the ceiling

$$ \int_0^\infty \mathrm{e}^{-x},\mathrm{d} $$

Feelin', funkin', amps in the trunk and I got more rhymes
