I really like the guy. That character of his is a lot of fun. He's not afraid to parody himself and he has even played a gay football coach. What really gave me an insight into the man was his reciting The Death of the Ball Turret Gunner during Mail Call.
From my mother's sleep I fell into the State,
And I hunched in its belly till my wet fur froze.
Six miles from earth, loosed from its dream of life,
I woke to black flak and the nightmare fighters.
When I died they washed me out of the turret with a hose.
