Ad libbing.

Straddling the night for the umpteenth time, unlikeliest freestyler
I'm doing my pantomime.

 Still got smiles, still standing proud,
denying only their dreams, who would see me in a shroud.

I'm not the toughest,
I'm not the prettiest,
I'm not te smartest,
I'm not the fastest.

I'm just a good all-rounder, quick on the uptake.
Which is not to say I'm immune to the mistake.
I swim and not flounder, scratching without a break,

I AM WHO I AM, what you see is what you get (ain't nothing here fake).
