I'll start...just off the top of my head:
The Federal Reserve and its goon squad, IRS
FBI
16 other "intelligence" agencies - which one can stay?
EPA
FDA
FEMA
NPR
ATF
DEA
OSHA
DOE - send education back to the states
DOT - transportation just happens; no govt teat-suckers needed
Dept of Commerce - commerce just happens; no govt teat-suckers needed
DHS - we already have a DEFENSE department to secure our homeland
DHHS - govt is unqualified to have any input about your health: they want you sick, dying, and in fear of sickness and dying, for maximum CONTROL over your life
Dept of the Interior - what, like without this we'd have only an exterior?
NEA - National Endowment for the Arts - People who value art and want to buy it should support artists by buying art - taxpayers should not be bent over and have tax dollars extracted from their colon for some misfit with matted hair and gingivitis to piss on a crucifix, tape a banana to it, and call it art

The Rural Electrification Administration. Formed in 1936 to build out electricity distribution to the sparsely populated parts of the country. There is now electricity in the rural areas. There is no longer any need for this agency. It now spends $3 billion annually to promote renewable energy.
