“…Kaz fits right in with the old masters. He brings their artistic sensibilities to our post-modern world. Sure, his ‘world’ is outrageous, demented, perverted and politically incorrect, but somehow it’s also charming, endearing, compelling and ‘cute’ in its own twisted punk way. As with all great comics, his characters are magically alive on the page. … The best compliment I can give Kaz’s work is that it’s %$#&* funny. … They don’t give out Pulitzers for hilarity, but Kaz deserves one. He’s a gag genius…”
– Patrick McDonnell, (MUTTS cartoonist)

“What primarily distinguishes Underworld is Kaz’s dedication to the gag at its most outrageously hilarious.”
– Booklist

“They heckle, harass, cheat, rob, bash, knife, shoot, and chop up one another with giddy glee, making Underworld the premier venue for rude, morbid, black, sick humor with a wall-to-wall grin on its disfigured face.”
– Booklist

“Possessed by a sense of anarchy that prevents the material from growing stale or one-note. Bawdy sex jokes commingle with more heady existential material, and inside-baseball cartoonist humor alternates with the occasional political gesture.”
