-Progressive commercials. Get that ***** Flo off the TV. She's not funny. She never was funny.
-Quizno's commercials. We get it, you have more meat on your subs, but I think you're missing the point as to why people go to Subways to buy the six inch turkey on wheat with lettuce. Also, those lame attempts at humor with the cats and talking subs make me hate your corporation.
-Firehouse Subs. "If a fireman says it's good, it's good."
-"Obviously not gamer girl trying to hard using cheap sex appeal to sell your crappy video game."
-Rehashed adds that are the same word for word by state, but change the names to a local store.
-Commercials which try to grab my attention by increasing the audio's volume. Fuck that. If your commercial is so loud it forces me to look at in anger, I don't care if you're advertising the second coming of Jesus Christ.
Commercials usually just plain suck. As a general rule of thumb, leave humor out of the commercials. It's amazing when it works, but when it fails, and it will 9 times out of 10, it convinces me to never again consider your product. If it can't stand on its own merits, and you have to cover it up with cheap gimmicks, you need to spend less money in advertising.
