RHH: What Are 5 Essential Verses a Hip Hop Head Should Know?

I don't know why this happened to come to mind, but I was reminded of
a Game interview I watched a while back, and the interview focused on
what he thought were the top ten hip hop verses fans of hip hop should
know. In this question though I'm only asking for five, if you want to
do ten, be my guest.

Feel free to elaborate on your choose of verses, here's mine (In no
order):

1 - DWYCK by Gang Starr (Guru's verse at 1:42):

3 - The Show by Doug E. Fresh  MC Ricky D (aka Slick Rick):

5: Rapper's Delight by Sugarhill Gang (First verse):

Those are just a few, I know that there are a surplus of verses that
we all love as hip hop fans. I won't hold anything against you if you
don't like these songs or verses, I know that they aren't the best,
but they are memorable for me. You don't have to put a link if you
don't want to, but it'll help the rest of us out.
