We have to admit, one of the best things about growing up was the television lineup on Saturday mornings. Before there were channels devoted solely to children, we only had one time a week when the TV was ours.

Generations of kids grew up with Saturday morning cartoons. Perhaps you're from the era of Quick Draw McGraw and The New Casper Cartoon Show. Or maybe you're a '70s kids who grew up with Jabberjaw and Dynomutt.

Aside from cartoons on Saturday mornings, there's another common thread that ties generations of us together.

That thread is a man name Don Messick, the prolific voice actor who appeared in more than 250 television programs. Messick started to lend his voice to cartoons in the 1950s and didn't stop until his death in 1997. That's a lot of Saturday mornings.

Messick is best remembered as the voice of Scooby Doo, but he has plenty of other identifiable roles (mostly animals) with Hanna-Barbera.

Let's take a look at some of them. Did you know one man was the voice behind all these roles?
