My favorite *ever* TV commercials were the ones AT&T cable had back in the day that made fun of dish companies (not because of that, but because it was funny)..
An example of one: This big satellite installer guy is on the roof, and the owner of the house asks him (from below) something about the TVs.. so the satellite guy just laughs and laughs and the owner steals his ladder..
The guy stuck up there asks for help, and a kid points at him and accusingly says "YOU'RE A BAD MAN!"
There's another where the guy goes to a woman's house and installs the stuff, and the woman asks if she'll be able to watch different things on the other TVs
"Of course not! When your husband's watching sports in the den, you'll have sports in the kitchen, sports in the bedroom.. it'll be like a sports bar!" and he goes on about all the things she could do as she's pushing him out of the house lol.
The single worst ads I've seen are comcast's.. they're so.. cheesey with the music and all, all the way down to the ethnical looking people and "Every time the dog sneezed *snow and white noise from old-ass TV* WE LOST THE PICTURE!"
Dishnet's ads aren't really funny, but at least they're not irritating
