It's incredible to think that Zits was only launched in syndication in the summer of 1997. Since then, the strip's leading teenager, Jeremy Duncan, and his mom, dad, and assorted friends have become a part of the American fabric and, more important, a part of our own families. Who else but cocreators Jerry Scott and Jim Borgman could so quickly work this magic through the more than 1,200 newspapers that now carry Zits worldwide? <P>Now comes Thrashed, the 9th collection of this incredibly popular strip. All the usual suspects are here: Jeremy; his friends Hector, Sarah, and Pierce; and Jeremy's long-suffering mom and dad. The crew find themselves wrapped up in all the angst and anxiety that life can muster, from keeping the gas tank above "E" to understanding the meaning of life. Through it all, Zits maintains its focus on the adventurous-if-sometimes-pockmarked journey that teens take toward adulthood. <P>This Zits collection of the past year's daily and Sunday strips is perfect for both teenagers and those who share residences with them, or ever did. Its warm and sympathetic tone brings humor and insight, even though the terrain is often rocky.
