How could this have happened?

There’s only one explanation: Mistakes were made:

Crocs

Microsoft Vista

Jon and Kate Plus 8

Fanny packs: Perhaps the last thing that broad-of-beam Americans needed was an accessory that emphasized their girth.

Abstinence-only sex education

The Apprentice: And any other television program, contemplated or actual, featuring Donald Trump.

McDonald’s McRib

Bruno

The Atkins diet: And the Metabalife diet, the South Beach diet ...

AIG

Knight Rider: All versions.

Jell-O shooters

Gladiator flip-flops: Actually, any flip-flops worn anywhere but to the shower or the pool.

Sport utility vehicles

Chocolate martinis: Actually any cocktail labeled as a martini containing anything other than gin or vodka and vermouth.

Tattoos
