These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moral Event Horizon: Al is a bit of a jerk, but one particular episode has him force a guest star to play guinea pig to his new invention, giving them a dinosaur foot. At the end of the episode, he's still around, yelling to the audience that Al must be stopped. Al isn't a jerk, he's a supervillain!
There's also the time Val Brentwood kidnapped a boy band to sabotage Al's competitor. Al was at first upset, but quickly decided to force them to play for him.
One-Scene Wonder: The show was filmed in the same building as The Tonight Show, and Al would often troll the halls trying to get Leno's guests to do a scene. A remarkable number of them agreed, like Drew Carey and Bill Mumy.
The Woobie: Cousin Corky gets the worst of Al's jerkassery. He tricks her into doing all his chores then abandons her to go on vacation, he aggressively forces her to take part in his talent show, and is just flat out insensitive to her. Plus it's clear she has some kind of self esteem issues.
