Sic 'Em, Mokuba!

'Nice hair, kid. You look like a black sheep dog; do you even have eyes?'
Mokuba blinked and glared at the bumper sticker in his hands. "A black sheep dog?" he said incredulously.
Seto snorted. "You do seem to be unable to figure out what a brush is for, little brother," he chided gently.
Trying – and failing – to run a hand through his tangled locks, Mokuba scowled. "I have more important things to do than worry about my appearance," he stated pompously.
Seto nodded and made a noise of agreement. "So do I, but then my hair is short enough to only need to run a comb through it once or twice. Yours is longer than Yugi's." he smirked.
Mokuba growled and started ripping up the note. "Speaking of Yugi… I can't believe he sent this to me." He huffed. "I mean, he's one to talk; looks like a fucking tie-dyed porcupine with that hair of his." A manic light gleamed in his eyes. Porcupine…" he mumbled thoughtfully.
Seto inched slowly back from his little brother-turned-malevolent menace. Some things even scared him – and Mokuba out for revenge was one of the few things that fell into that category.
