Know What I Mean?

I guess this is as good a time as any to tell you
That Greg and Sam didn’t go by "Greg" or "Sam" anymore.
Heck, they’d been the only two people alive for two years,
And there weren’t a lot of people around to say
“Hey Greg,” or
“Hey Sam.” You
Know? So they’d both taken to thinking of themselves
By different names. Greg called himself “Shooter,”
And Sam always thought of himself as “Dude,”
But, like, he really thought of himself as “Dude.”
