Anyway...

Patrick Star. He got an award for being lazy.

Baloo the Bear

Baloo, the sloth bear is a friendly, likable, laid-back character who likes to take things easy.

First and second pig brothers
the familiar fable of the 3little pigs

The first two pig brothers are more interested in play than work. they build their homes from sub-par materials, and soon experience homelessness due to the big bad wolf.

Straydog

There's a Private SNAFU short called "The Goldbrick" in which a lazy fairy called Goldie the Goldbrick teaches SNAFU how to be lazy and sneak out of his duties--he ends up being killed. The kicker--Goldie is on Japan's side and knows that this is a surefire way to win the war for the Axis if other soldiers follow in SNAFU's footsteps.

"Porky's Bear Facts" features a lazy neighbor bear farmer who sings that "Working Can Wait." Winter comes and the bear and his dog are starving--Porky reluctantly lets them in to have dinner with him. The bear hasn't learned his lesson though.

Saltyboot beat me to Dodsworth--but he had second short called "A Peck o' Trouble" in which he convinces a kitten to catch the woodpecker for him--out of the pretense of teaching the little guy to cat birds. Best line: "Too bad they don't have elevators in these trees."

The Powerpuff Girls (the original ones) had an episode called "Cop Out" which featured the worst cop in Townsville, Mike Brikowski--yep, every single cop stereotype you can think of revolves around this guy--doughnuts and sleeping. After getting deservedly fired, he tries to kill the Powerpuff Girls. This isn't a bad cop gone bad--it's a bad cop gone worse!
