Well now Duo realised he was a fucking weirdo because somehow, for some reason, Wufei getting pissed off was really kind of hot and he damn near popped a boner as he was marched away from the stunned Oni.

Anger aside, as soon as they were past, Duo was trying not to laugh. More at his own bizarre reaction than anything! And when he spoke, there was definite laughter in his voice. "I think he pissed himself. You're good at that, Wu."
