“Got to Be Real” by Cheryl Lynn
seconded
Another vote for the OP’s suggestion.
So far listening to the other offerings I am convinced that we are right.
Jungle Boogie by Kool and the Gang.
Flashlight.
This. GUTF is the song I crank on the stereo in my classroom when I think my students are acting too white. 
No, we haven’t been, but that sounds exactly like the issue we were having a few months ago. There was a 4-5 day period in May in which it’d give an “acquiring signal” message, and be silent, about 95% of the time. After those few days, it started acting normally again, and we haven’t had an issue since.
Mos’ Scocious, Dr. John
Heh, it’s a great song, but it’s highly repetitive. Which is why I think Superstition wins out.
Yo Pretty Ladies around the world … Word Up…Just for the codpieces, I felt that they created funkatronic.
Superstition is a mind-blowingly awesome song. Same for Machine Gun. Both worthy contenders.
I submit for the thread’s pleasure:
Stevie Wonder and his band performing Superstition live on Sesame Street. Check out the little kid with the loose afro just completely rocking out.
Seconding of course JimmyFlair’s link to The Commodores performing Machine Gun on Soul Train
God, I wish I had been alive back then.
I had forgotten about Jungle Boogie - great, great song, but for me it’s only legendary because of its use in Pulp Fiction.
Sorry guys, but Flash Light still wins out 
You cannot resist the Bop Gun. Sir Nose D’VoidofFunk couldn’t, sucka!
or War- Lowrider/Spill that Wine. Carribafunk.
Ok… my final nomination. Booker T and the MG’s- Green Onions
Old thread by yours truly: Your favorite funkadelic song. I’m still going with Stevie Wonder’s I Wish but Robert Randolph’s Ain’t Nothin Wrong with That is powerful funky.
I have to say that every song mentioned in this thread rubs that special spot in my brain that says, “get your fat white ass up and dance”.
However, for funkiest song ever, I think the OP had it. To me Thank You (Falettinme be mice elf agin) is the proto-funk song… It is what I hear if someone mentions funk without mentioning a specific song.
I was thinking of "I Need More Love"by Robert Randolph for contemporary funk. (The studio version is a bit better than this live version).
But for all time, the funkiest song belongs to the funkiest bass player which, to me, is the backbone for funk. Bootsy Collins’ (Bootsy’s Rubber Band) “Bootzilla”. You can feel that bass in your soft palate.
I’m real partial to Magic Sam and Freddie King … John Lee Hooker (really early stuff), and add early Howlin’ Wolf to that mix. Charley Patton, Tommy Johnson … you’d be surprised what might turn you on. Prewar blues is all full of double entendres & weird “English” … intreresting. :eek: Well, hell, so is early postwar Chicago blues. Snooky Pryor. Johnnie Young, a mandolin player: “Let Me Ride Your Mule.” You get the idea.
What about the theme song to Sanford and Son? That’s dirty funky.
Also “Bold Soul Sister” by Ike & Tina Turner, which features Tina rapping about “things and stuff” over a groove like that of Sly & the Family Stone’s “Sing a Simple Song.”
Or Funkadelic’s “Loose Booty,” whose hard-to-hear lyrics make me imagine the song is extra nasty.
No love for James Brown? I know he’s the “Godfather of Soul”, but his shit is funky to me.
“I Got You (I Feel Good)”
“Man’s World”
“Hot Pants”
Also, Red Hot Chili Peppers “Sir Psycho Sexy”.
