Red Forman (That '70s Show)
Kurtwood Smith is the quintessential verbally abusive dad, although he often eschewed subtlety in favor of insulting nicknames.
Example: "So, this is how an engaged high-school dumbass with no car, no job and no money trims the hedges."

Al Bundy (Married with Children)
While Eric Forman didn't always deserve the insults his dad leveled at him, Al (Ed O'Neill) called it like he saw it, pointing out Kelly and Bud's failings as children as well as human beings.
Example: "Bud, if you need money, you should do what a wise man once said, "Yip-ip-ip-ip-ip, mu-mu-mu-mu-mu-mu-mu get a job."

Arthur Spooner (King of Queens)
Technically Doug's father-in-law, Arthur still lived with him, and he was played by Jerry Stiller, which meant Doug was regularly mocked for his weight and stupidity.
Example: "You know, we're quite a team. Like Jake and the Fatman. Needless to say, I'm Jake."

Frank Costanza (Seinfeld)
While Jerry's father was usually fairly complimentary (even if they were back-handed compliments), Jerry Stiller was there to be mean enough for both of them as George Costanza's perpetually disappointed dad, whether George was living at home or elsewhere.
Example: "My George isn't clever enough to hatch a scheme like this."

Martin Crane (Frasier)
As the ex-cop father of two staggeringly pretentious psychiatrists, John Mahoney's Martin had plenty of material to work with.
Example: "Try playing the role of a sane person."

Ken Titus (Titus)
He didn't live with his two sons, but the elder Titus (Stacey Keach) caused them enough psychological damage when they were kids to last them well into adulthood.
Example: "You're late! This car's a piece of crap. Where did you get it anyways? It looks like an old man's car! I'll be inside. And park it around back!"

Frank Barone (Everybody Loves Raymond)
Whenever he would stop by to visit, Frank (Peter Boyle) had plenty to say about his sons and his wife.
Example: "I could have eaten a box of Alpha-Bits and crapped a better interview!"

Alan Eppes (Numb3rs)
This show isn't cancelled (yet, anyway), but you can't deny it's got some brilliant (brain-wise) characters in it. Played by Judd Hirsch, chess-loving Alan is proud of his scientist and FBI agent sons, and even lives with one of them, although he is also fond of pointing out how clueless both of them can be about important things like sports and romance.
Example: "That was better. You almost hit the ball."
