I'd have to go with Bugs Bunny but Mickey Mouse and friends should be in there. Homer is probably the best for modern day cartoons. I was very fond of Scooby Doo myself. Not so much Scrappy though. Hated Scrappy, actually. So did my kids. I didn't have to deal with Scrappy as a kid.
My kids have no idea what "Saturday Morning Cartoons" was about either. It used to be that basically cartoons ran from 7am - 11am Central and that was about it. Although, Bullwinkle was on Sunday.
Oh, Bullwinkle is a great cartoon character too. So many good classic cartoon characters. Way too many modern ones. Sponge Bob now comes to mind.
Too much coffee today.
