A lot of people liked the the fast talkin' Fed Ex and Home Depot commercials because they're intentionally funny. But when a client creates a fast talkin' ad by accident, it's just sad.
The Discovery Home Channel gives Kraftmaid Cabinetry a 5 second billboard before their commercial. Normally, the billboard is short and sweet - "This progam was brought to you by so-so". However, for whatever reason, the client decides to stuff their 5 seconds with about 30 seconds worth of copy. It just sounds horrible.
