Time Warner Cable/RoadRunner - multifaceted stupidity of obscene proportions
Verizon Wireless - fucking up and locking down phones; Contracts, contracts and more bullshit contracts
USPS - laziness, pathetic inability to track anything
Motorola - epic incompetence. Decent at hardware, but fucking clueless with software

Politicians/idiots

George W Bush - dragging down the average american IQ
Dick Cheney - opting not to go by "Richard"
Some moron from Alaska - helping popularize stupidity and hate
