Describing one's hate for something with the phrase "the white-hot intensity of a thousand suns." This has officially passed from cleverness to cliche.
Comic strips featuring the main character watching television for two frames, then giving an "I can't believe this shit" look to the reader in the third frame, used as a device to lampoon media or current events. Garfield has fallen into this many times, along with too many other strips to count, including Candorville (aka Lemont Brown in the LA Times), but the worst violator of late is Boondocks. This is lazy, not visual, and generally a poor use of the comic strip medium. Just go ahead and draw a strip about TV shows if you hate using your own characters so damn much.
