He often makes funny face like this picture!
He is not a technical player.
But, I like his bass line especially in "Longview" in Dookie.
He writes most songs of Green Day.
I like his voice and lyrics!!
His live performance in Bullet in a Bible is really exciting!
His powerful drum sound is the base of many songs!
He seems have strong muscles, doesn't he!?
His good drum plays appear especially in American Idiot!
